I'm creating both DVD and Blu-ray versions of a music video using DVD-A 6. I have two audio tracks people can select on their player's remote: One is a 5.1 mix in AC3 format, and other other is stereo PCM to avoid lossy compression. I have several commercial concert video DVDs with these audio options, so I know it's possible. But I don't see how to assign two separate audio formats in the Project Properties dialog. It seems the three choices - PCM Stereo, AC-3 stereo, and AC-3 5.1 Surround - will be applied to the entire disk. If this is addressed in the manual or Help I can't find it. Thanks!
