MPEG video really isn’t intended for editing, it is intended as a final delivery format.
Because of this, many programs like FCP an Premiere Pro don’t play that well with it.
The missing audio has to do with the way the mpeg audio is written into the file. the normal work flow that I am aware of would be to use a conversion program to turn the MPEG footage into Quicktime Dv format and edit that.
