OK, this is what happened to me today. I swear it happened. How many have a DD 7.1 system with only 5 speakers hooked up? OK, probably just me. Been having all kinds of audio problems with local feeds, and HD channels. Sometimes I would get DD ProLogic, mostly PCM-48 (whatever that is) Been working on the room anyway so this isn't something I just tried to do to see what would happen. Had 2 speakers in the living room as remotes that weren't needed. So I brought them into the TV Room and hooked them up and OH MY GOSH! All the channels/commercials are back. Everything is Dolby Digital 2. Cept for the XM stations which say PCM so I don't know what they should be. Does this sound right? I suppose it's possible, but why would some channels work and others not and why did it start on the 145 release on 3/30? Kinda weird huh? So I guess if you have a 7.1 system and only 5 speakers, try hooking 2 more up to the L/R Center channels and see what happens. Sorry for the rambling but that's what happened here. I would be curious if anyone can use this as a solution.
