[mythtv-users] DVB recordings fail with: 'Warning: Unsupported bandwidth parameter'

[Mike Perkins]

Yesterday every DVB recording failed with zero-byte files created. There were no 
changes made in the last couple of days, but I did migrate my MBE from Mandriva 
to Debian the previous week-end - this coincided with Digital Switchover Phase I 
from the Hannington transmitter. All last week I had no problems with any 
recordings.

I tried some LiveTV this morning to see if it was one or other of my two tuners 
but both give the same result.

I googled the message but the results in the main seem very old, so that's why I 
am asking again.

The whole log of my LiveTV test is as follows. Notice the messages which occur 
immediately on startup, one per virtual tuner /except/ the first:
