I am completely frustrated with my HD PVR. In live and watching recoded shows, the signal drops and I get blue screen for 6-8 seconds at a time. This happens A-LOT. Try watching an on demand movie and having the lost signal 50 times during the movie of course during key dialogue times!! I have called, unplugged, reset, and traded PVR's. I have also changed my HDMI cable. What else is there to do except divorce Shaw and get Apple TV?
