My pvr is doing this as well. It shuts down and re-initializes/re-boots many times during an episode or movie on Netflix (channel 422). Telus was here two days ago and gave me a new pvr and this new pvr is doing the exact same thing. For what it’s worth, it sits on top of an ikea cabinet, not inside. The old one sat inside and I thought that’s what was causing it but this new one has never sat inside the cabinet. Help 😞
