Audio loose sync after resize with DGAVCdec, glitches... Impossible to rip?

[phate89]

Hi... I have a ts h264 1080 tv show recorded by myself that i'm trying to convert with avisynth... I already tried with other episodes and i had no problems but with this i don't know how to rip it..
I used DGAVCdec to import the video...
I put avcsource() in my script and try to play it with audio andthey are in sync... but there's regularly a glitch in the video... when i play with media player classic (directshow) i don't get that glitches...
so i try to resize the video..when i do it the audio loose the sync (i tried with lanczos to a sd resolution)...
So i tried ffvideosource and directshowsource... With both the audio is already not in sync even without resize it...
with ffvideosource there's no glitch, with ffvideosource there's some sort of flickering.. it repeats some frame..
So i try to look at the original video in original language to see if it was ok... it is 6 minute longer than my version (48 against 42)... but there aren't cuts... so my guess is that they do something to reduce the length of the video (some sort of time compression)...
Anyone has suggestions about how to compress this video?

DGAVCDec is deprecated. This does not mean that it will never work, only that it will fail on some H.264 content that uses coding techniques that the decoder library shipped with the last version of DGAVCDec does not decode correctly. That you see glitches in the video suggests that you are looking at some content that has this problem.

I suggest using DGIndexNV or ffmpegsource (in the latter case, try remuxing to Matroska first).
