problem opening divx5 encoded file

[neverever]

hi there all
possibly a question that been asked and answered before and if so appologies but could not find a previous post answering it...
i have an AVI bideo captured from TV with Ferro encoded with Divx5 (5.02 i think) and audio is uncompressed PCM i think. It opens fine in media player, zoomplayer, BSplayer etc but when trying to open it in virtualdub (want to cut out commercials) it throws a wobble saying something about not being able to decompress video frame. If i jump to key frames it does it but very strangly forwrd jumping key frames show some different frames to backword jumping key frames. tried to open it in AVIutil but it doesnt want to play it (pict stays still and garbaged with squares). Tried AVIedit but there is no picture showing... Tried to rebuild index and strip/rebuild index with Divfix and no results... any ideas???
cheers

just to clarify...
the actual error message i get is "Error decompressing frame xxxx" - i used xxxx because it is not confined to specific frames (i did my homework and serched again through the old posts...) - i can jump randomly forward and when press play the error message would come up again.
tried a solution i seen recomended in an old post using avisynth script (specifing the frame rate) but it didnt work
I have opend the files with Gspot and it all seems ok (all codecs in place - 4cc is DX50, codec is Divx5, 25fps, PCM audio)

more details...
just checked the file information in virtualdub for the said files and under decompressor it put "REALmagic Mpeg-4 video codec" - I didnt even know that i had the realmagic codec installed, i thought that it would use the ffdshow or divx5 to decompress...
do i need the realmagic codec and if so how can i get virtual dub to use different decompressor (assuming that this is the reason for the error messages)?

after uninstalling and reinstalling divx 5 i finally found a solution...
looking through the tsunami folder on my pc i found a utility called 'video codec swapper' where i could deactivate any codec - i deactivated REALmagic and tried virtualdub and presto it associated the files with divx5 codec and did what i asked it to do...
thought i better post it in case anyone else has a similar problem...
cheers all
