Hi all;

I recently downloaded a few music videos and converted them to iPod via iTunes (I'm using a Mac if this matters). One of them works just fine... it's mp4, whatever that means, I'm not that well versed in the newer formats). All the others (in mpg format) don't have sound when converted to iPod, although they do have sound when played through iTunes or Quicktime. Is it the format that is preventing the sound from converting, and if so how do I convert .mpg to .mp4 (if its even possible).
