WinTV HVR-850 again not working
I'm getting "Timed out, no signal" on channels that (rightfully) have no signal, but "Timed out, no channels" on those that previously worked. I tried upping the timeouts to 10 & 12 seconds, but to no avail. The machine hasn't been restarted, nor the device removed since it was working last. There's no reason that I can see for MythTV to no longer be able to acquire these channels.
This is frustrating. If you haven't already, DO NOT purchase the HVR-850 (or HVR-950 variant). Get an HDHomeRun or similar and be happier.
