when will the Virtual Dub team finally fix the audio sync , on avi's that have been converted from VOB to avi-mp3 ????
Anyone here that tried doing this conversion knows there is always a Audio sync error,
but still no fix has been provided in virtualdub.
Also I see problems in commercially available programs that when you do this conversion with another program , The Audio sync is perfect ,but the video resolution gets stuffed up by doing something else. like changing 720x404 to something stupid like 720x480 and people end up with Long Faces.
Also I have come along problems where some VOBs have 2 or 3 sub-audios in them and so when the conversion gets done you can here a mix of audio from original track mixed with one of the sub-audios ,which co-exist in one single VOB

Why are you using Virtualdub directly on VOBs when that hasn't been a sensible workflow in a decade?

They'll never 'fix' it because nothing's broken. Any audio synch problems are caused by the person creating the AVI.

I've done several thousand myself and never had an audio synch problem. If you're talking about the VDub error message when opening an AVI with VBR MP3, I believe more recent versions of VDub can handle MP3 audio OK now. Someone that uses it can confirm, I'm sure.

AVIs usually (but not always) use square pixels while DVDs don't, and are encoded with DARs of 4:3 or 16:9 to be resized during playback. You're speaking out of ignorance (as with everything else in your post). Read up about aspect ratios in Doom9's article here:

Not if the conversion is done properly and played back using a decent player (not WMP).

Which DVD VOB has a resolution of 720x404?
================================
well if put a 16:9 DVD resolution in a dvd player and use an old 4:3
television ,u see a black line on the top and one on the bottom.
When u recode this to avi and not change the resolution u see a stuffed up resolution, unless u change this to 720x404 this will happen ,but with 720x404 u see no change and it looks just like the original DVD !!!

So you are complaining that DVDs use a resolution of 720x480?
Do you know anything at all about aspect ratios?
