I'd check to see if the signal coming into the HDPVR is good.  Can you hook up 
the inputs to a TV or a monitor to verify?    You could also try hooking up a 
TV or monitor to the pass through, but it's never been clear to me if that's 
the same output from the capture.  But it might help indicate if the problem 
is with the HDPVR.

Are your HDPVR module parameters correct for the inputs?  For component input, 
  the parm is default_video_input=0 and for SPDIF default_audio_input=2.  You 
can check the current settings by looking at files/parms under 
/sys/module/hdpvr/parameters.

You can also try loading the module with hdpvr_debug parm set to a non-zero 
value.  A value of 1 should give some extra debug info in the syslog.

Do you get any messages in the mythbackend log?  You might want to try 
starting that with -v record,audio,important or -v most and see if that gives 
any insight when you start a recording.
