[MPlayer-users] mencoder: creates unusual AVI?

I am trying to create an .avi movie which can be played with something 
else than mplayer. The movie has no sound and is produced from a 
sequence of several hundred jpeg images with this commandline:
mencoder mf://im/Composite00*.jpg -mf w=1500:h=1163:fps=2:type=jpg -ovc 
copy -oac copy -of avi -o im/Composite.avi
I have also tried the options -ovc lavc -lavcopts 
vcodec=mpeg4:mbd=2:trell, but the result is the same: plays fine with 
mplayer, but not with quicktime.
When I try to play it with quicktime, I get the message that additional 
software is needed, and I'm redirected to 
If I play the movie nonetheless, it's just a black screen.
I'm doing this on a Mac with OS 10.5.6, the mplayer/mencoder binary 
1.0rc2-4.0.1 (yes I know it's not the latest, but I can't compile it 
myself), and quicktime 7.6.
Any ideas?
