Hello all,
For those that do not know, it seems that DVD2AVI suffers from a frameloss problem.
Neuron2 at Doom9 has been working on it and has come up with his own new product named DGMPGDec.
You can find it's latest version here http://neuron2.net/fixd2v/decodefix.html.
Please note that in order to use this new D2V tool you need to use it's new Mpeg2Dec3.dll that was rebaptized DGDecode.dll.
Also tools like Moviestacker or CQMatic that can read/parse D2V files will need to suffer an update in order to be compliant with DGMPGDec.
In terms of Moviestacker we'll have to wait for Muaddib's return to ask him.
You can use FitCD v1.2.3 until then as it is already updated.
As for CQMatic we'll have to ask Karl to update it whenever he has some time available as he has been very busy lately.
Although I don't use DVD2AVI anymore (due to MEncoder usage), I think this one is worth giving it a try.
Cheers all

Hi Rui,

You must be talking about CalcuMatic
Here you go:
http://www.kvcd.net/CalcuMatic.exe
That's CalcuMatic version 1.1.01, which now supports .d2v files created with Donald's "DGIndex", plus the regular old style .d2v files
Please test it and let me know

Wasn't that frame rate big fixed in 177.3 unofficial version 1.10 or 1.20 or 1.30 (the versions before DgIndex)??

I don't like the new DgIndex to be honest - eberything need to be changed to accomodate it (media player classic won't play Dg's d2v's, etc).

I do not see where is the "news" in all this.

The fixed mpeg2dec3 dll and DVD2AVIdg (former name of DGIndex) exists since FOUR MONTHS ! There is ABSOLUTLY NO NEED TO UPDATE TO THESE VERSION.

Updating to these realease alraeady gave us lot of problems with D2V files that mades crashed avisynth for some obvious reason (probably because the people didn't use the mpeg2dec3 corresponding to the actual DGIndex version they used).

You can continue to use the old good 1.76 that never gave any problem. The frameloss problem is more theorical that practical (it happens in very rare case and loosing ONE frame isn't so much important).

Note: Moviestacker 2.1 already use mpeg2dec3dg

In fact if a Mpeg Videostream in a VOB does Begin with BB after the I frame, the first Frames in DVD2AVI will be dropped. Also at the very end 3 Frames will be dropped.

That explains to me that the AC3 "Delay -xx" isnt really existing in the VOB as a settet delay ... but its mentioned in the demuxed AC3 Filename as it compensates! that frameloss at the beginning of the via d2v transfered video data.

If you will be 100% correct, use that DGIndex one, but (IMHO) few Frames loss incl. a compensation of audio delay in besweet when reencoding (which I always do) then IMHO for my personal taste there will be no problem, as In my cases all works fine and no audio desync results.

BUT if you only do re-encode Video via mpeg2source and avsiynth, you should use mpeg2dec3DG (or the latest one) as if you dont reencode audio, the result "could" be recognisable out of sync.

But maybe I missed something in that big Doom9 discussion there ...

As for me, I've never EVER had any issues with DVD2AVI 1.77.3, so I'll stick to that

Hi Phil,
No, in fact these are no news what I have posted.
I didn't post it as being news, in fact.
I posted so that others that don't know about it, may learn that it exists.

True. There's no need to update, Phil.
As there is no reason for me to sell my '82 Ford Fiesta (since it still works fine), and buy me a new one, right ?

That I didn't know about Phil .
Otherwise maybe I wouldn't have posted it in the 1st place.

Well then, if that was the reason, then people should really start reading the readme file that comes with the
software they download from the web .
In this case Donald explains it in the file that his D2V clone only works with the correct Mpeg2Dec3.dll clone,
that is DGDecode.dll, and that it has to be the same version that comes with the DGIndex you are using.
Need to say more about it?

No Phil, there's no theory about it.
You can check that yourself by creating d2v files from DVD2AVI v1.76 and from Decodefix/DGMPGDec at the same time.
Please compare the frame count from both (I get the feeling that you have already done that ).
Now do it with half a dozen movies, and tell me about it.
I am aware that you know 10x or maybe more about video than I do.
But unless someone prooves Donald is wrong I am sticking with the facts.
D2V files created with Donald's DVD2AVI fix produce more frames than Jackei's DVD2AVI do.

BTW I PMed Muaddib about it and he told me that as soon as he fix the GPL issue in Moviestacker,
he will also update it for DGMPGDec.

@Karl,
Thanks for the fast Calcumatic's update .
I'll give it a try this evening

@all
Bottom line:
There's actually no other plausible reason for anyone to move from Jackei's DVD2AVI to Donald's DGMPGDec,
than if you actually worry about loosing frames and trust in Donald's work.

I don't use DVD2AVI on a regular basis anymore because I've been encoding all my KDVDs with MEncoder
from VOB files and it's built-in filters.
But since I'm also testing VMesquita's FreeENC I am testing both at the same time with AVISynth 2.5.5a.
Very good results so far, may I say.
Cheers everybody

Okay.

The only diff is that I have doubt about your '82 car run as wall as it does 10 years ago. But DVD2AVI 1.76 still work as well as it always worked before DGIndex was out

Readme file ? What is that ? Can you eat it ?

OT question : I never had any info about why there are so much new release of DGIndex. It seems to me that they are fixing bug they introduced themselves in the previous release !

I did, and I always loose 1 frame maximum, no more !
Inc seems to say that you can have also 3 frames lost in the end, that I never had.

Quote:

I don't say he is wrong, I'm saying that THE LOSS DOES NOT HURT SO MUCH. As I told, I never lost more than one frame (when I actually lose one !)

What is the average number of lost frames you noticed in your own test ?

Quote:
D2V files created with Donald's DVD2AVI fix produce more frames than Jackei's DVD2AVI do.
Did you used PAL or NTSC ? Perhaps there is also a problem with the "force movie" feature. I did PAL only.

Quote:

So I hope he wil be present on the forum AS LONG AS PEOPLE WILL HAVE PROBLEMS WITH SCRIPTS. Because I refuse to answer to any questions about it anymore !

Hi Rui, I agree with you about Mencoder especially PackShot by Inc. It produces some great quality video from my DVD sources.

The only thing I have against PackShot and MencoderME is that fact you must rip your movie to one whole VOB & I am reluctant to convert my FAT32 partition to NTFS to overcome the 4Gb limit as my drive is shared on my home network with a couple of machines that use WindowsME.

Yeah! Bad comparison I did
Jackei's work still does work as good as in the day it was released.
My 22 year-old car is definitly not running as smoothly as in the day it left the factory

Well that only Neuron2 can answer. I don't follow his work at D9 because I have unregistered there.
I would be very stupid for unregistering and afterwards go there again to check the forum, right?
Anyway even if I'dd go there I would be too lame to press the search button and find his threads

Maybe run the test again? All the 5 movies I tested so far gave me 3 frames less.
All tests done with:
-Avisynth 2.5.5a
-DVD2AVI v1.76 and Mpeg2Dec3.dll from 20030728
-DGIndex and DGDecode.dll from DGMPGDec v1.0.12
-Simple avs script only with mpeg2source and resize
-and VDubMod v1.5.10.1 to read the avs file info and get the frame count.

Well I don't know if it hurts bad, but I would bet it hurts a tiny little bit at least.

3 so far out of 5 movies.

Only DVD sources here and they're all PAL only too.

Who were you pointing at? Muaddib&Moviestacker or Neuron2&DGMPGEnc?
If you're talking about Muaddib (never saw Neuron2 here...) he will come back but it will take some time, though.
His life has been very busy too (as mine...)

Well you never know.
Today I'm only producing real backups with MEncoder&built-in filters.
Tomorrow I may be using MEncoder&Avisynth scripts or FreeENC&avisynth scripts.
Don't you think I should worry?
Not to say that (you should know by now ) that I care for all our community too, besides myself.
Cheers

Edited to add the utilities used in the tests!

The reason for the many releases was that there were some new features added by request, such as working with transport streams, and these had some issues which have now been fixed. The regular MPEG-2 decoding engine has worked well for a long time, although I found a bug some time ago which was corrected immediately. This bug occurred because the encoder had created a very strange GOP in the beginning of the movie which then crashed DGDecode. I don't know what the result would have been with DVD2AVI 1.76 but I don't think it would have been anything good.

I will probably do then. I did test with first relaese of mpeg2dec3dg and perhaps since then, other frame loss fixing have been added.

Now, 3 frames is still not so bad. So after all, anything turn arround this :

What is better : take the last version to fix the frame loss but have a risk to fail on problems that didn't exist before, or keep the version that never gave you problem beside this 3 frames lost ?

That is a common problem with all software indeed...

Hi Phil,
Don't forget about one thing in my 1st post: "maybe we could give it a try".
I didn't say:"let's go for it!"
As said, I have been testing it from times to times and never gave me any problems (DVD2AVIdg 1.3.0).
And the newest DGMPGDec 1.0.12 hasn't failed me so far and I've used it with 6 or 7 different movies, now.
So, I'll say it again: maybe we could give it a try.
If it prooves to be safe and if it saves 3 frames per movie, maybe we could recommend it (along with
Jackei's version too) but only after thorough testing!
And after transport stream issue being definitly fixed (maybe boulder can advise us when it does get fixed).
How does that sound to you Phil ?
Cheers m8

All the issues should be fixed, and as I said, the regular MPEG-2 decoding engine has worked fine for a long time already.

EDIT: Something about this DVD2AVI thingie reminds me of the Avisynth 2.0x vs. Avisynth 2.5x case we had earlier

Didn't pay attention to that thread at that time

Karl, it is actually 1.0.6 not 1.1.01. Please clarify it.

Hi dongxu ,
Well, that's probably another issue with the recent change of ISP.
I'm sure Karl will take care of that soon.
Cheers
