I'm using the current Mplayer from ATrpms.  I tried installing
libx264, but mencoder doesn't see it.

I am able to encode for the Ipod Touch using:

mencoder -ofps 25 -of lavf -lavfopts
format=mp4:i_certify_that_my_video_stream_does_not_use_b_frames -af
lavcresample=44100 -vf-add harddup -vf-add scale=320:240 -oac lavc
-ovc lavc -lavcopts
aglobal=1:vglobal=1:acodec=libfaac:abitrate=128:vcodec=mpeg4:vbitrate=256:keyint=25
Test.vob -o Test.mp4

So even though it's not h.264, it's a great picture.  Does anyone know
if there is a quality difference between mpeg4 and h.264?

I suspect "format=mp4" did the trick.

BTW, I get alot of "1 duplicate frame(s)!" messages.  I assume it's
normal since I get them all the time.  Is there a switch to turn them
off?

Thanks for the help.
