Yeah, no fix for the pixelation problem.
The issue must be a tough one to solve. Could be a PlayReady issue since it seems to be on copy once content.
Weird thing is that it isn't apparent as other times. Some premium channels would have the pixelation strip once a minute or so. Other times it will be fine for 20 minutes. For example, I flipped on a movie on HBO2 HD as I typed this and within 2 minutes got a pixelization strip. Waited another 10 minutes before hitting submit and haven't seen another one.
