I captured a VHS MPEG2 clip using Pinnacle USB Moviebox and the
audio is in a mp2 format. My DVD player does not play mp2 audio.

In the settings option there is a field where you can convert the audio
to LPCM format.

Do I have to split the MPEG2 clip into elementary .mpv and .mpa
streams first before I convert the audio during authoring or can I
just import it and have it convert it to LPCM on teh fly during authoring?

Thanks for the help
