Another DVDDecrypter (3.0.1.4) Bug ?

ookzDVD · 25th January 2003, 06:26

@LightningUK!

I would like to report a very "Strange" fenomena.

If I rip the DVD in .IFO mode and choose the "Stream Processing",
then I choose the desire stream usually, the video, audio (.AC3) english, and subtitle English. And I DON'T choose "Demux" the
AC3 stream to external file. So the video+ac3+subtitle is still
in the result .VOB(s).
Then I use SubRip (v1.14) to parse the subtitle from the result .VOB(s) so I save the subtitle result into subtitle1.srt

Then...
I rip again the same DVD with the same setting above except for the
.AC3 I CHOOSE "demux" . So the result .VOB(s) in only containing
video+subtitle. Then I use the same SubRip setting to these .VOB(s)
and I save the subtitle into subtitle2.srt.

After I compare the subtitle1.srt and subtitle2.srt
is not the same. The subtitle2.srt in about the middle of the movie
is somehow speed up about 2 minutes in my case of Ice Age R1 DVD.

That's why if I rip with the second method, I always got the subtitle
out of sync. but if I use the first method, the subtitle is sync perfectly.

So... Is it a DVDDecrypter's bug ? or SubRip's bug ?

PS. I really need your opinion.

Thank you.

Update:
It's happen again with K-19 R1 DVD.

All I can assume is that subrip tries to read something sometimes that isnt there when you strip the ac3 stream out.
Im 100% sure nothing else changes by you just demuxing the ac3 instead of leaving it in the vob.
I guess its more of a limitation than a bug.
Have you posted this in the subtitle (subrip) forum (whatever that might be?!) ?

@LightningUK!,

Thank you for the confirmation,
I guess it's related to the SubRip's bug, since it's only
happen with certain DVD, I've found 3 so far :
Ice Age, K19-Thw Widowmaker, and The Signs.
All are R1 DVD.

Bingo!

zuggy confirm that it's related to the SubRip's problem.
and it's no solution so far, so better avoid demux the .ac3 tracks,
just leave it in the vob(s).

Thank you.

...or go double safety and do a second subtitle only rip with vobsub giving you exact index file which can be processed further in subrip.
Also this way, subtitle process is quite accelerated.
It never failed so far. And the extra 12 min rip time are worth it!

My 2 Euros
