MyHD cannot acquire a signal while SageTV is running. Why? I don't know. I can receive and play TV with both WinTV (through a PVR-250) and MyHD running, but when SageTV is up and running (even in Sleep mode: not recording or displaying TV), MyHD starts and says "NO SIGNAL FOUND". That's a deal-breaker for me. I need the capability of recording SD broadcasts with the PVR-250 while I use the MyHD MDP-120 to view/record HD programming. Anyone know of a solution for this (other than forget about SageTV)???
