On the aspect... the video seems to be in the original DVD PAL format of
720 x 576, which will look odd when played if the correct aspect isn't
If you want the video to automatically play at the correct aspect
(without using mencoder and setting aspect) then I would resize it to
soemthing acceptable to you using -vf scale=xxx:yyy
Can't help you on the audio front, sorry.
