It's been talked about a lot, but I took the most simplest way to connect two 5.1 devices to one set of 5.1 analogue inputs. I basically made a set of Y-adaptors (could've bought them, but I had the bits so I made them instead) and I connected two DVD players 5.1 analogues to the Y-adaptors and the straight into the amp. The results were absolutely fine. As long as only one unit is on at a time, there is no loss in sound quality or volume. I was quite amazed. So all I have to do now is get a Blu-ray player (waiting for the Panny BD50) and I can connect up with my Arcam DV137 to the same inputs with no worries.
