Anyone see FotP last night? On NBC HD, the Dolby Digital stream had an LtRt flag according to my receiver, and there was no dialogue - just stereo music & FX. When I flipped to the non-HD analog NBC channel, it was normal. Afterwards, Scrubs on NBC HD was fine (flagged as 5.1). WTF? Would that be a network, local station, or cable company screwup?
