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 
applied.

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.

Thanks,
Phil.
