Wasn't sure where to post this but...I buy most of my cds off of ebay. Is there any way to tell if a SACD is only in stereo versus multi-channel? Also, I have a cd made by Silverline. The title is "E-Klek-Trik" by David Diggs. The case and the cd itself says it is a dvd video/audio. On the back of the case it says "Supports DVD-Audio, Dolby digital and DTS formats". I'm not sure I understand what supports means here. There is no menu that allows you to pick from different formats.

I have a Pioneer DV-578A player and a 990. I can only get it to play via the 7.1 connection.

Any thoughts would be appreciated.
