Received this on the 4th; HR44/700. I am getting constant freezing since the update (like every five minutes) which then goes to blank screen on live TV; hitting previous channel will restore picture, but clears the buffer. I have checked signal strength, and all is good. Numerous 771-signal loss on sat 1/2 errors, that clear after a couple seconds. All cables are tight and in good shape. I had zero issues before this update.
Recordings playback pixelated, freezing occasionally, but nowhere near as bad as the live tv issues. Have tried numerous resets, ( both guide, and RBR) ran all smart tests, all internal hard drive tests, etc. and all passed. Forced reinstall of software (I think anyway, I reset and input 02468, and it went through the updating process). No calls to support yet, but will on Monday if it doesn't improve, because it virtually unwatchable right now.
Do you have another HDMI cable ? If yes change out the cable.
If you have them or can put your hands on a set of Component cables ( 5, Red Blue and Green for Video and Red and White for Audio ) hook the unit up with that and see if the problem goes away.
If it does it is an HDMI Handshake problem.
