Re HD Master: I was wrong about this -- I misread the Panasonic site. The BD10A only does DTS HR, not DTS MA. That's too bad, but if the replacement carries 7.1 forward, I guess it won't matter.The Panasonic DMP-BD10/DB10A does NOT do DTS-HD Master audio, the Sigma chipset used in that and many other early BD players does not have the horsepower according to Sigma themselves to handle MA. It does do DTS-HD High Resolution, however there aren't many discs with HR on them. ... Three of the latter are on their way this year so far, the Panasonic DMP-BD50, the Denon DVD-3800BD or the Marantz BD8002. All will decode all HD audio, are at least profile 1.1 compliant and all are supposed to have 7.1 analogue audio outs.
Re new BD players with 7.1: that's great news!
