Yeah I can't say it's bothered me. In 2 years it has only happened twice, so thats not bad, ecspecially once you think about it as thats only once every 8700 hours and at most only lasts 1 hours after that. And yes, its run by an HDMI cable (Monster, unfortunately), but I don't think it is that, because if I go into GUIDE and thumb through the recorded DVRs, I can scroll through the list at normal speed with no clipping of the guide, its only the moving picture that clips at full size, but what is even more bizzare is if I am in guide and have the TV picture minimized in the top right corner, the live TV plays without any clipping or interuption at small size, it's only when I go back to full screen viewing that the screen clips... Very strange.
