I've no idea why it refuses to play it. Your commands look alright to
me. I've a bunch of scripts with iPod presets, which you may try out
and see if it'll work for the g5. I don't have an iPod myself hence
can't really test here
http://h264enc.sourceforge.net/index.html
http://xvidenc.sourceforge.net/index.html
I haven't got any reports from users yet that the iPod presets in
these scripts don't work
