Hi folks, New S3 HD owner with a strange problem here. I've only had the new box for a few days (upgraded from an S2), but every now and then, I'll be watching a show and the TV will just go grey. I change channels, and same thing... just a blank grey screen on every channel. No messages about signal or anything. Just to be sure, I've checked the signal strength and such in the Settings area, and everything appears fine, and other TV's in the house and the cable internet are still going strong. A reboot of the Tivo fixes it every time... until it seemingly randomly decides to go to a grey screen again. Any ideas? Oh, and boy do I have a horror story to tell about Charter and my cablecard installation... but that's another thread. TIA.
