Hi,

Should I be able to 'watch' (well listen) to radio stations in MythTV 
via LiveTV?

I'm installing MythTV 0.24.2 (combined BE/FE) on Ubuntu 11.10 in the 
UK.  I've tried this with both DVB-T ans DVB-S2 tuners with the same 
result, that is it fails.

I perform a scan (DBV-S in thie case) and can then watch TV stations 
from the FE.  However if I switch to a radio station, for example Radio 
4, the OSD remains on the screen for 30 to 60 seconds, during which time 
I can hear the radio station.  Then the FE exits LiveTV with the error 
"Video frame buffering failed too many times." on the screen.
If I go and look in the FE log I see lines and lines of

     Player(1): Waited 100ms for video buffers 
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAU

with a few lines like this mixed in

     RingBuf(/home2/mythSGs/livetv/7754_20120131220454.mpg): Waited 0.2 
seconds for data
         to become available... 18672 < 32768

Then I get

     Player(1), Error: Waited too long for decoder to fill video 
buffers. Exiting..
     TV: Attempting to change from WatchingLiveTV to None
     BrowseEnd()
     RingBuf(/home/mythSGs/livetv/1700_20120129221157.mpg): Waited 0.2 
seconds for data
         to become available... 7112 < 32768
     RingBuf(/home/mythSGs/livetv/1700_20120129221157.mpg): Waited 0.2

     Player(1), Error: Failed to stop decoder loop.

      Error: Unknown audio decoding error

This seems to be the same whichever radio station I choose.

Oh, and another issue.  Whenever I go back to LiveTV it is now stuck on 
Radio 4 (channel 1004 on my system).  How do I get out of this?  That 
is, how do I get LiveTV to go back to starting on BBC 1 (or anything 
other than the radio station it can't deal with).
