[mythtv-users] All of the sudden: HD3000 + QAM - "Off Air" messages

[Byron Poland]

All of the sudden my HD3000 which is fed by my cabe (comcast)'s QAM
feed is not able to tune to channels in Myth (after several months of
working flawlessly).

If I watch the backend log:

running azap on the same card and same channel (10_1 is on qam 119)

$ azap 119

seems to get a lock.  And running dvb traffic, and cat
/dev/dvb/adaptor0/dvr0 > test.ts

gets a ts stream with all 5 subchannels including the one refereneced
as "10_1" in myth.


Does anyone have any thoughts on this?

Thanks.
