Usually the picture quality pretty good. However, I have just been watching Boardwalk Empire. Fairly static scenes are OK, if a bit soft. However, anything with fast motion seems to be a bit jerky and blurry - almost like an XVID encode when the bit rate has been set way too low.

I'm hoping they haven't dialled back the bitrate to use it for a different channel, but have no way of measuring this. It's not unwatchable - but it's getting close, and is pretty darn disconcerting.
