1.3 I've encoded into MPEG2 format on my Mac, but still doesn't play?

Output in MPEG2 on Mac software tends not to use the format required for audio playback in Adscreens.  We suggest you use a format converter program or simple edit software such as Nero Vision Express to save the file in MPEG2 (either DVD or SVCD resolutions) to resolve the problem.
