I should give some more info, what I did:
(using MEncoder from cvs)

I tried several times, here are (simplified) versions of the commandlines:

mencoder a.avi -o a.mp4 -of lavf -oac faac -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=512 -vf scale=320:-10 -faacopts br=128:raw
-ffourcc mp4v
(also tried without "raw")

mencoder a.avi -o a.mp4 -of x264 -oac faac -ovc lavc x264 -x264encopts
bitrate=384 -vf scale=320:-10 -faacopts br=128:raw -ffourcc avc1
(also tried without "raw")

Also tried all of these for creating .movs.
I had no luck with these. MPlayer and Vlc accept the files, but not Apple :(
Sometime there were MEncoder-crashes when trying to use the
"-ffourcc", but these were fixed recently.

If you use an other audio-codec (or "-nsound") I had some luck, to let
quicktime open the file, but not the ipod of course, which does only
accept aac.

bye,
hco
