Thanks for the reply, but this didn’t seem to do anything. I tried changing the -aspect to the appropriate ratio and the output was unchanged. What exactly is the -aspect tag supposed to do? Removing it had no obvious effect on the output.
I did manage to fix my problem, however, by figuring out what the proper dimensions of the movie should be to fit my player. So for example I started with a movie that was 704x304, which shrinks to approximately 224x97. Apparently the padding needs to be in multiples of 2 pixels, so I used 38 pixels for the top and bottom, leaving 100 pixels for the movie (slightly stretched but not really noticeable). So in the end I had:
-r 20 -vcodec mpeg4 -vtag DX50 -s 224x100 -padtop 38 -padbottom 38 -b 700k -qmin 3 -qmax 5 -mbd 2 -bf 2 -aic 2 -cmp 2 -subcmp 2 -bf 0 -acodec libmp3lame -ar 44100 -ab 128k -ac 2
