Ohh, okay.
I knew digital could only carry 2 channels of audio, so I was wondering how in the world DVD-A could manage to do it over SPDIF digitally and uncompressed. I'm thankful it wasn't something with the software on my computer.
Thanks for clarifying that.
Since I have a computer, for me to do that, I would have to buy 3 1/8 to RCA adapters (to split the 3 outputs for front, rear, center/sub) and 6 RCA cables just to do DVD-A. Then I'd have to move my SPDIF line to my motherboard SPDIF out. Then I'd have to switch the mode on my software every time for a DVD-A disk. For just one DVD-A disk I have, doesn't seem worth it.
Do most DVD-A disks also have a dolby digital side or selection?
