Frame errors in VDub <<<<<HELP

[section16]

I am trying to join 2 AVI files together. They have different audio sampling rate's so I have to remake and save as avi in Vdub. I do this for the 2 parts and then join them together succesfully. Then when I watch the big AVI back I see the audio sync has drifted after half way through the film so i check the original 2 AVI files with Vdub framechecker. The 1st AVi has 0 bad or undecodeable but the 2nd AVI shows me this **249 frames masked (2 frames bad, 247 frames good but undecodable)** What am I supposed to do to correct this?

Any1 help me with this please?

Bugster man, are you about??

Ive just got the latest version of virtual dub which has the bugs fixed soi no more errors about MMX state now.

I have scanned the AVI film and it has 98000 bad frames so when I re save it it ends up about 230MB when it started out as 715MB. I notice on the playback of the fixed AVI the audio sync is out, probably due to the amount of bad frames removed from the AVi..............I need to know if there is a way to fix these rather than delete them as Ive 4 films here with big amounts of bad frames in them all

Some advice would be nice

Please

I now know that you cannot fix bad frames, only delte them which can result in a big chunbk of the movie missing The only way around it is to download / aquire it again............
