Since the au retune I haven't been able to get mythtv to tune to channels 9 or 10 on boot. If I shut down mythtv and manually run a w_scan then restart mythtv it works (without touching anything in mythtv), so I'm guessing my card is failing to automatically detect one of the various dvb-t parameters that must have changed, but w_scan is figuring it out...
Does anyone know exactly what the retune changed? All the frequencies appear to be the same...
no idea what actually changed with the retune, but i just shutdown mythtv-backend and then ran mythtv-setup, deleted all channels, and then re-scanned. delete and rescan seemed the easiest/least hassle method (and i vaguely recall doing the same thing once or twice before).
my myth box has been working fine ever since.
I think I figured it out. One of my tuners seems to be able to autodetect all the settings in the transponders (except bandwidth which I needed to manually set to 7), the other tuner requires setting up most settings individually. When I would restart MythTV and find things working again, what was actually happening is that by chance I was using the good tuner so it all appeared to work again. Once I set the code rate, guard interval, and transmission mode manually it all started working again (or at least it seems to so far...) Thanks James
