mahler123,
I also have a Pioneer Elite BDP 09 that I use for video. The audio through the "Pure Audio" mode is great, however, initially it wouldn't play Blu-Ray until it had a firmware update. Who invents this stuff? It's like buying a car that won't run unless you take it to the dealer for the 30-60-90,000 mile tune ups. It reminds me of the "universal" players that will only play SACD, but not DVD-Audio (or the reverse). My Oppo 105D doesn't have that problem, as it plays everything!
