Always glad to have your input, rob.
anecdotal advice will say that these decks like you to stick with one media type (I use Sony -RW discs) for a limited amount of time (I only use the discs about 50 times each to be extra safe).
I would tend to agree on this. In fact, I'd go one further:
- Dedicate a stack of DVD-RW that are going to ONLY be used with this machine. Don't share the discs with computers. Remember to only use 2x DVD-RW, and never 4x DVD-RW.
Although the DVD burner drives used in computers are technically the same ones used in DVD recorders ...
... because a DVD recorder is nothing more than a one-task computer, with a specialized integrated video-oriented motherboard, a MPEG chipset for the CPU (LSI Logic chipset, in the case of these JVC decks), possibly an analog and/or ATSC/QAM tuner, and a DVD burner....
... anecdotally, there are some differences.
Once a computer burns a DVD-RW, odd things tend to happen with the discs. For example, the disc will suddenly only read (or burn) in certain drives, players or recorders. Not all drives are the same, and I often think the variable burn quality found drive to drive tears up the discs. The phase-change crystalline-metallic alloy materials just don't seem to stand up well to wear, used on lots of different systems. Theoretically, I know it should not matter, but it does in practice. And as you know, this site values practical application above that of book theories.
I made the mistake of using some 2x DVD-RW in the computer, and those 5 discs are now unreliable. Sometimes the disc will "burn" (record) in the JVC deck, but nothing is recorded. Or the disc won't finalize. It's a nuisance. So I've set aside about 100 discs. When dedicated to the machine, I think the lifespans far outreach the conservative limit of 50.
What I'm using is this:
- Fuji 2x DVD-RW
- Sony 2x DVD-RW
- Memorex 2x DVD-RW (Ritek ID)
- Maxell 2x DVD-RW (Maxell ID)
- Pioneer 2x DVD-RW (Pioneer/PVC ID)
- TDK 2x DVD-RW (TDK ID)
Offhand, I don't remember the media ID's on the Fuji and Sony discs. The MID on the Sony might be Sony. The MID on the Fuji is probably Mitsubishi (MCC,MKM).
I also use these, without issue:
- Verbatim 16x (1x-16x) DataLife MCC03RG20 DVD-R (inkjet or branded)
- TDK 16x branded RITEKF1 -- not that I would suggest it, but I know it works, as I've used these discs extensively for testing needs.
I ran into issues with 4x Verbatim inkjet discs (Prodisc plant), as well as 8x Sony (SonyD1 Daxon Taiwan) discs. However, the media was fine in all of the computer burners -- the firmware in the JVC just doesn't hold up well to "new" discs. Remember that the LSI based JVC DVD recorders have firmware from 2004 and/or 2005. While the 16x MCC discs are undoubtedly functioning off a default write strategy -- it works well!
Dust is another issue.
Keep units covered when not in use for extended periods of time. Be VERY SURE the power is off, if you cover it -- you don't want to trap heat!
Once again, I don't know how much science and truth behind those helpful hints of wisdom, but I've experienced a lot less in the way with quirks and problems with this deck by obeying those basic rules. YMMV.
Nah, sometimes the science/theory doesn't match up with what actually happens anyway. I understand quite a bit of this tech, but am still dumbfounded on a regular basis -- maybe once a month. It all comes back to human error, to be honest. The intricate coding of firmwares and software is really what gets us. Most issues I run into are programming snafus. Sometimes they (companies or people) admit it, sometimes they don't.
