I have the Motorola HD DVR (3400) box and have noticed macroblocking (I think??) on the TCM HD channel. It happens every two or three minutes. It also happens on the QAM channel on my tv (Toshiba 37HL95). Usually there is a sound dropout followed by the macroblocking. Before I report this to Eastlink I would like to know it anyone else is experiencing this on channel 668. It's not happening on any of the other HD channels and not happening at all on channel 198 (TCM SD). By the way, I'm in Summerside, PEI. Anyone?

There is a difference between macroblocking and pixellation. Macroblocking is due to compression of the signal and typically happens during fast movement in scenes, or scenes with fast changes - strobes, confetti, etc.

Pixellation is due to a poor signal, even temporary and is typically much "harder-looking" than macroblocking. Check your signal, S/N ratio:

I guess "pixellation" is the correct term for what I'm seeing on Ch. 668 and only after the sound dropout. If it is a signal strength issue, wouldn't it happen on other HD channels as well as TCM? I checked my QAM channel for TCM and the audio dropouts are not happening on that feed (I initially thought they were). I guess a call to eastlink is in order. Thanks for your reply.
