You can use a Demultiplexor Like the One in Tmpgenc "Mpeg Tools".... Just Run Tmpgenc and go to "File" to "Mpeg tools" and then Load your Mpeg file in the "Simple Demultiplex" and then click "OK" and it will Demux your Mpeg file into a seperate audio and Video file... Womble Mpeg2VCR also has this Feature.... Cheers
