I tried searching and seen a lot of problems with people and live tv, but I could'nt find anything specific with the hd-pvr. I have an HD-PVR hooked up component cables and analog audio to a STB. I also have a HVR-1600 hooked up to the analog tuner with straight analog cable. Whenever I watch live tv through the hd-pvr a lot of times i wil just get a black screen then goes right back to the main menu. Other times it will work but whenever I go to change channels it goes right back to the menu. I have tried both coreavc and the arcsoft encoder, firewire channel change and the blaster, as well as live preview mode enabled and disabled and get the same results...Heres my logs if that will help any...thanks..
