Hello,

I suspect this is a bug: when I try to read my .avi file (taken from a
fujifilm digital camera) I get this mplayer output and no success:

And when I do it with -vc mjpeg it works:

The annoying thing is that I want to convert this file (MJPEG, raw pcm audio) 
to DivX/mp3 with mencoder, but I've had no luck, probably due in some degree
to this bug. Does anyone have any idea ? (I could post the video online, but
it's 16Megs)

Thanks.
