[MEncoder-users] Help cleaning up avi file

[Alex Samad]

Hi

I have some avi files, (some downloaded, some made) and when I play them
with mencoder I get

[mpeg4 @ 0xb19b60]Invalid and inefficient vfw-avi packed B frames
detected


what is a simple way for fixing these files, I thought something as
simple as

mencoder -oac copy -ovc copy <infile> -o <outfile> -vf spp

But that doesn't seem to do anything, I don't really want to re encode
because I don't want to loose any quality

output from file test.avi 

Test.avi: RIFF (little-endian) data, AVI, 624 x 352, 23.98 fps,
video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)
