Decompression Problem

[WeedVender]

I have a couple of Video files that are litteraly screwed.
The files are encoded at a 352,240 resolution at DIVX 3.11.
Here my problem, I can see the entire video with no problems but when I encode to MPEG or Divx5.0, I get this error that it cant decompress the frames. I get it at the same spot every time and In virtual dub and any other program that allows views of video, I can see the video past that certain point.

Any suggestions?

Corrupt data at that point? scan for errors with divfix making an error log then in virtual dub delete these corrupt frames and resync the sound for the rest of the movie (if u have corrupt frames the sound will go out) before converting

Your movie has some corrupted frames. In VirtualDub, select Video/Scan Video stream for errors... This will mask corrupted frames, i.e. afterwards the video will pause while the audio goes on. Video playback will proceed at the next correct key frame.
This scan takes pretty long, so if you hate waiting (like me ) go to the first damaged frame, set the selection start there, then go to the frame before the next intact key frame and set the selection end. Select Video/Mask selected frames and save to AVI again.

I did that but it didnt work

OK so sometimes the progs are not perfect at picking up the corrupt data, it's happened a couple of times with me before. In virtualdub go to the point where this shit is happening and press play, watch the avi, if there are any disruptions in the video file (e.g. small blocks of colour that should not be there, messy picture) then it is corrupt. Perhaps try deleting the data between the 2 keyframes and then resync for that point? or split it into 2 avis, one before the sync prob, one after. Resync the 2nd avi in vb before saving and then remerge the 2 avis to 1 again

Can you make that clearer?
