[mythtv-users] Couldn't find a matching decoder for: rbuf://...

[Ryan Daigle]

I'm having issues watching live TV.  When I choose Watch TV, all I get is a
blank screen.  I can escape out of mythfrontend and the log statements that
are spit out to the terminal say:
 
"Couldn't find a matching decoder for:
rbuf://127.0.0.1:6543/media/recording-buffers/ringbuf1.nuv"
 
I've gone through the appropriate ALSA installation and all seems to be well
with that (I can play sounds and /dev/dsp is never tied up with another user
while myth is running).
 
All devices (/dev/dsp, /dev/video0) are owned by mythtv as is the
recording-buffers directory.
 
My mythbackend.log has no error messages, just the usual:
 
"adding: noel.ryandaigle.com as a remote ringbuffer
Changing from None to WatchingLiveTV"
 
I have a PVR-250 and am using a Creative SoundBlaster Live! Value.
 
Watching a recording works just fine, but live TV just shows a blank screen.
 
I have a suspicion that changing my hostname halfway through the
configuration process may have mucked some stuff up, is this possible? 
Where does it try to map the URL to a decoder?
 
Please help!
