An "Alpha" version of the new IsoBuster 4.4 is available for download.

This pre-release version is for the purpose of gathering feedback and comments.

Its available here

This version supports extracting recordings in their native VOB format from the RD-XS hard drive to a Windows PC. Its been tested with the RD-XS32, 34, 35, 52, 54, 55, KX50 and the XV34SJ (JPN) and XS34SB (UK) with NTSC_M, NTSC_J and PAL_B.

This is not the same thing as extracting "clips" or "pieces" of recordings. Full recordings, even if fragmented have been tested and works.

I made a video of the process here

I wish he could do it with the Philips 3575 as well.

I get really annoyed when it adds a copy protection flag to recording. Because then I have to use a Grex between my Philips and RCA, and re-record the shows. (Even a TBC fails to remove the flag, only the Grex works. Ironic, since the Grex is useless on VHS Macrovision, causing color/brightness quality side effects.)

But even the RCA 8020 would be nice.

I'm assuming the Toshiba hard drive must be removed, place in a computer?

I was thinking the Pioneers and Magnavoxs might be interesting to look at. The Mags descended from the Philips tech if I'm not mistaken. The break seemed to come around the 2160 or 513.. which might be a good starting point and include the 3575. The later Funai models that I've looked at don't look like they deviated from the previous models as far as the HDD data.. but I'm not certain.

Was that the RCA 8020 or RCA 8030 you were interested in?

Regarding removing the hard drive from the Toshiba.. not necessarily. I didn't want to complicate the video or confuse the procedure. Removing the hard drive for the video was the easiest to demonstrate.

But there are many options today.

IcyDock for example makes some fine optical SSD ejection trays that could fit in the space of the DVD burner. Older but just as viable were some port selectors available in 2010 for autoswitching the drive connection between the recorder motherboard and a PC eSata port with a USB cable "like" connector.. they are harder to find today, but I have one from the UK. And Digikey sells some modern EVBs for manually switching SATA connections under control of a raspberry pi. A pizero could sit inside the case and "export" the drive as an iSCSI target over wireless.. but that's a fringe idea even for me. Windows has a native iSCSI initator so it could (in theory) mount the drive completely wirelessly so IsoBuster could use it remotely.

The problem is trying to keep it simple without confusing people, demonstrating a smooth path to success. I'd also prefer not to frankenstein or permenantly modify these recorders, just update them in an aesthetically pleasing manner. -- thats kind of why i think the 'ejectable' drive through the DVD slot would be most portable across most brands of recorder.. optical media for these is getting scarce and moving a small pocketable drive between recorder and pc would be hard to beat for convenience.

RCA DRC8030N with 80gb HDD, uses Zoran chipset, awesome recorder for cable/satellite. I am getting concerned about the DVD drive in the unit, it's acted odd at times in recent years.

Philips DVDR3575H with 160gb HDD actually isn't as good quality, but it could record 16x9 from ATSC OTA unlike the RCA. But the file had to be re-flagged as 16x9 once ripped from disc.

I also have the JVC SR-DVM700US LSI-based recorder with 250gb HDD, and to be able to remove recordings from it would be a huge time-saver. The only fear I have with the JVC is that the HDD is not replaceable, so I don't want to screw with it, tempt fate. Rather not touch it at all. In fact, I don't know that you can access HDD contents at all.

I don't even care about aesthetics. It's a tool, utility matters to me. I don't have room for it to have guts splayed out is my only requirement.

I'll look into those recorders. The toshibas took most of a month and a couple weekends. To a degree support for other brands may depend on interest in whats already supported. If no one shows interest, we might loose interest too. Its kind of a spur of the moment thing, and people seemed to get negative about it in the past. There is nothing like a wet blanket on a topic to kill a project.

I kind of like looking at these puzzle boxes and testing for the developer.. I don't think he has access to any of these recorders, but he's curious, fast, creative and very thorough at handling problems. He really amazes me.

I have a DVM700 bucket of bolts, works except for the burner.. so I can probably look at that too.

The JVC DR-MH20, MH30, MH300, DVM600, DVM700 are probably all identical as well.
But to me, the Philips and RCA would be more useful.

The LiteOn (Polaroid DRM-2001G clone specifically) may end up being easier that those, maybe even easier that the Toshiba. And I'd like that one done as well. I currently have 2 of those full of recordings, dreading offload time to DVDs and ripping. Unlike most other recorders, the HDD could be replaced without any special tricks (that I recall). My Polaroids were upgraded to 250gb and 500gb drives, from the 80gb stock.

See this: https://forum.videohelp.com/threads/...1G-customizing
And: https://www.avsforum.com/forum/106-d...le-w-dvdr.html

I've not looked at that recorder in years, need to read those threads again myself.

Welp.. knock me over with a feather.. DVM700 burner is okay, dubbed a JVC recording to a toshiba DVD-RAM and played back tosh and jvc recordings from the DVD-RAM with no complaint, seems to be totally working except for a dim display. Also the DVM700 hard drive looks partitioned slightly, though not officially.. something up front and then acres of space and maybe recordings. I'll have to look more into it after I get some sleep.

I have resisted testing this theory, so far.. but reading about other people removing their hard drives and putting them into a PC and trying to return them.. only to find they have to use a service remote, or wipe and reinitialize their hard drive.

I thought I would offer this "unverified" theory.

The Windows PC has an "automounter" the first thing it does when it detects a new hard drive in the system, particularly one it thinks is unpartitioned is it throws up a message that asks "in a positive tone".. "Do You Want to Initialize so that you can Use the new drive in this system"

That means it will "write" a Master partition and Book Record (MBR) to the top of the drive, obliterating whatever is there.. "damaging" the DVD/HDD recorder drive. They should tell the "automounter" [NO] I do not want to use the drive in this PC. (a highly unintuitive reaction).

It may be that if more people went against human nature and denied the automounter request, fewer drives would be damaged and have to be reformatted when put back in the DVD recorders.

IsoBuster doesn't need that MBR at the top of the drive, its perfectly happy recognizing strange new partitions and formats.. and making up virtual partitions and file system in its main window without ever writing to the hard drive.

As I said its a theory..

While testing with all of the Toshiba models, I always denied the "automounter" request to "write" to the DVD recorder hard drive, and never had a problem putting it back into the recorder.

There is a command prompt way to disable this automounter behavior, but its really for advanced users. But, I would think for people who often take a DVD hard drive and put it in their PC, using this command might save them a lot of grief.

In fact I really can't think of why its the default.. when you try to format a brand new "un-initialized" drive. It asks the same thing before asking for the details about the format you would like to perform.. so its kind of pointless. Its like "auto opening your CD in file explorer, every time you put a CDROM into the tray".

Except in this case it causes "damage" by default, and makes the user an accomplice.

Well, I'd like to think that's many of us on this forum.

The Philips DVDR3575H has an identical filesystem to the MDR513 its coded as HDDfs 00.70 and appears to be in "roughly" VR format. The Toshibas used a UDF format to contain their files, the Philips and Magnavox appear to simply dump them on the hard drive with a single file allocation table.

The developer has other priorities until March.

JVC DR-MX1 was part of the JVC series which included the MH30 and MH50.. I can look at the MX1.. by association the hard drives in the MH30 and MH50 may use the same storage format.

It helps that the 5.25 drive bay holders are mostly plastic these days, it keeps the costs way down.

Found a little nugget in archive dot org

LSI and JVC press release for MX1

Aug. 10, 2004 - LSI Logic Corporation (NYSE: LSI), a leader in innovative digital media processing technologies for the Digital Home, today announced that JVC (Victor Company of Japan, Limited) has selected the LSI Logic DiMeNsionTM 8652 (DMN-8652) DVD recorder system processor for use in the unique JVC "3-in-1" DR-MX1 digital video recorder. By tapping the diverse features integrated into the single-chip DMN-8652, JVC's DR-MX1 integrates the capabilities of a DVD recorder, VCR, and hard disk drive (HDD) recorder into a single, high-performance, full-featured product.


Nothing earth shattering 15 years later, but the MX1 was also the premium model of the MH30 and MH50 the DMN-8600MK manufacturer kit was the basis for many dvr recorders, and its demo screen closely aligns with the color palette of the JVC product line

DMNB600.jpg

The HDD appears to be based on C-Ware TFS2 and may have used the VxWorks operating system. Clues from similar recorders based on the same encoder card in the Netherlands and other European countries suggested it was a VMG0 or VR format, perhaps unfortunately it "may" be encrypted.. i've read programs off it.. but they are skewed in some odd manner, could have been the signal source.. or it might be in big endian format.. not sure. To tell I'll have to pull off some of my recordings, so I know the condition of the signal going in... this was only a preliminary quick glance at what there was to work with. The overall 10,000 ft view however was like many other recorders.. except something odd lurking at the very bottom of the drive the recorder keeps pinging.. might be an encryption key cache.. but I have no way of knowing.

JVC Press Release from 2004 on the "Lupin" series

JVC Co., Ltd. has announced the introduction of three new DVD recorders with large capacity HDD that make long term archival quality recordings. The three models all support high speed, high quality dubbing from HDD to DVD. But the DR-MX1, will support 6 way dubbing between VHS/HDD/DVD.

Also.. found two LiteOn LVW-5045, would that be close enough.. or a walmart ilo?

A quick look shows they seem to use FAT32 but I neglected to look at the file folders. I don't know how hard they will be to figure out how the vobs go together.
