at first quick look, its wrong stuffing bits, combined with bad luck (normally 
ffmpeg/lavc detects & works around it)

u can try mplayer with "-lavdopts bug=0" to force bugfree type decoding, it 
fails
or try mplayer with "-lavdopts bug=16" to force padding/stuffing bug type 
decoding, it works

btw, could it be that xvid doesnt add stuffing bits if the last bit ends at 
byte aligned boudary?
