Hi. I have this simple problem. I want to substitute the MP3 audio in have om my AVI with an AC3 audio stream I can rip from the same DVD I used when I made it. I think to use VirtualDubMod (Stream____Stream List; Add the AC3 + Desable the old one; [OK], set Video on Direct Stream Copy , Save as [F7]).
I can demux the audio traces in many ways from a VOB set (DVD2AVI if there's also the video), VOBEdit in any case...
My problem is this:
the file VTS_01 - Stream Information.txt shows that on the AC3 audio streams there's a delay of -80 ms.
[A strange thing: when I 'decode to WAV' the sound with DVD2AVI I never observed a delay (why?). I'm afraid now that I will]
So, the questions are:
1) how can you fix the A/V delay you know exists, when you want to make an AVI (on DVD authoring you simply add a 'delay' number, but here you can't)? If you have 'delay -80 ms' what do you have to set, and where?
Please note: I don't want to make again the AC3 file. I just want to tell VirtualDubMod to take the delay into account, if there's a delay (will it exist , such a delay?), Or , if there is not such a possibility, can I extact , from a VOB set, an AC3 stream which has 0 delay, I don't know, with ReJig or something else...
2) why, when you simply 'decode to WAV' an audio stream with DVD2AVI, you don't notice a delay? Is the 'zero delay' a feature which exists always on DVD2AVI or only when you 'decode' (and , when you 'demux' is noticed)?
