sound problems

[rab622]

I am also having problems with a movie i downloaded , the sound is ok as avi, after i save the wave with virtualdub and encocde with tmpgen it is way off it starts about 7 seconds early , if i try to uncompress audio with virtualdub it was( ACM failes to suggest audio decompression format). then (AVIOutputWAV: The handle is invalid).
any help would be much appeciated .

The ACM failure would be because there is one or more frames that are screwed
