[mythtv-users] PDATRANSCODE: Mencoder Issue

I just got an Ipod Touch to replace my Dell Axim X51V for watching
Mythtv video.  I'm trying to update PDATranscode to emcode video for
the Ipod.

This command using FFMpeg works:
nice -+19 ffmpeg -i  $VIDEODIR/$FILENAME -f mp4 -r 30 -vcodec mpeg4 -b
384 -qmin 3 -qmax 5 -g 300 -acodec aac -ar 44100 -ab 192 -s 320x240
-aspect 16:9 -title $TITLE $VIDEODIR/pda/$TITLE-$STARTTIME.mp4 -v -1

But this command using Mencoder produces a file that I can't import into Itunes:
nice -+19 mencoder -ofps 30000/1001 -af lavcresample=24000 -vf harddup
-of lavf -oac lavc
-ovc lavc -lavcopts aglobal=1:vglobal=1:vcodec=mpeg4:acodec=aac -lavfopts i_cert
ify_that_my_video_stream_does_not_use_b_frames -oac lavc -ovc lavc -lavcopts agl
obal=1:vglobal=1:vcodec=mpeg4:acodec=aac  -o

Any suggestions?  Anyone had success encoding for an Ipod using Mencoder?

BTW, I think Mencoder produces a better quality picture than FFmpeg,
that's why I like using it.
