I guess "-af volume=13:1" is to fix the low volume of most DVDs?

Does that mean your command above will produce broken files without
sound? Or only if I would replace "vcodec=mpeg4" with "vcodec=h264"?

:-/ Why do you specify "format=psp" in your example? Is this a typo?
Do I have to use -ofps 24000/1001 or can I also use 30fps or 25fps (for
PAL TV shows)? What are the limits of an iPod?
