I was in BB today buying some DVD's and decided I need a new DVD-A. I was browsing and noticed now(I don't think they were there before) that they(DVD-A's) have stickers saying they will play in any DVD player. What does this mean? They can't get the full benefit of DVD-A through just any DVD player, can they? They must be only to use the DTS or 2 channel music of the disc right? Or if the DVD player has multi channel outs is it possible to play DVD-A on a regular DVD player. I dunno, I seen this today and was curious as to what it means for people with your normal run of the mill DVD player.
