[mythtv-users] changing channels on master doesn't work

[Brian J. Murrell]

I've just updated to master 7768ebc on both my FE and BE and while I can
start live tv and it works, changing channels yields a whole lot of:

2011-09-05 12:56:49.290028 E [6353/21918] DeviceReadBuffer

After some time it finally gives up and the FE goes back to the menu.
Trying to select to watch live tv again yields:

2011-09-05 12:57:32.338477 E [6353/6374] TVRecEvent
recordinginfo.cpp:961 (InsertProgram) - RecordingInfo::I

13:00:00 2011)
             title(Canada's Worst Driver)): recording already exists...
2011-09-05 12:57:32.408480 W [6353] RecThread mpegrecorder.cpp:631
(GetFilteredAudioSampleRate) - MPEGRec(/d
                        is not supported by ivtv driver, using 48000 Hz
instead.

and the FE reports "Error opening jump program file".  I can rectify
that by going to the live tv group and deleting the previous program of
that name.  I suppose I could also wait until the channel that the live
tv tuner is sitting on is showing another program.

Cheers,
