[mythtv-users] HDPVR tuner error in Mythtv 0.23

[Shawn Flynn]

Hello,

I am trying to setup a new slave backend with an HDPVR encoder attached, but
am having a bit of trouble getting MythTV to use it. Hopefully someone here
can point me in the proper direction for troubleshooting this. 

The system in question is a CentOS 5.4 i386 machine with the current
mythtv-0.23-fixes packages from atrpms. The HDPVR appears to be working
outside of mythtv as I can 'cat /dev/hdpvr-0 > test.ts' and play back the
resultant file in mplayer with both audio and video.

Mythtv-setup allows me to select the HDPVR device and appears to take the
settings without error. My current settings are as follows...

Mythtv-setup
  Capture Cards
    [HDPVR : /dev/hdpvr-0 ]
      Card Type: H.264 Encoder Card (HD-PVR)
      Video device: /dev/hdpvr-0

      Input Group 2: Generic
    [HDPVR : /dev/hdpvr-0](S-Video) -> (None)
    [HDPVR : /dev/hdpvr-0](Composite) -> (None)

Mythtv-setup exits and saves the configuration without complaint.

Starting mythbackend on the slave gives me the following log output...

------------------------------

All looks good so far, but here's the hitch. When I fire up the frontend I
can't access the tuner on that slave backend. Looking at the frontend
'Information Center' > 'System Status' > 'Tuner Status' I see a status of
'Tuner 2[HDPVR:/dev/hdpvr-0] has an error' and the tuner does not get
selected for recording or live TV.

Can somebody give me a clue as to what debugging option I should turn on in
the backend to provide me with more detail as to what the aforementioned
'error' might be?

All thoughts and suggestions welcomed,
