I've been looking at some DVD recorders and it seems that they have digital audio out but only left and right analog audio in. Does that mean that they only record in 2 channel? I'm not sure how I would use that. I currently run everything (DVD player, Dish PVR receiver) into my receiver and it gets decoded there. The receiver has digital audio out for recording but that's not much help if the recorder doesn't have digital audio in. It looks like I would have to use it like a VCR when recording and then what happens to all my 5.1 sound?
