I watched "History Detectives" this evening that I'd recorded from my local OTA PBS HD channel 28-1. Exactly 12 minutes in it paused, no pop-up screens or anything just still video & no audio. After some playing around with the transport keys it finally let me FF past the spot and continue playing. I could Rewind back and play thru the same spot again without problems, no pixelation or anything to indicate a signal problem. The exact same thing happened again at around 35 minutes in.
