[mythtv-users] Sound issues with the pcHDTV 5500 analog tuner

Jesse:

Apart from the sound issue - were you able to get the HD5500 to scan in
both NTSC and QAM-256 channels?

I can only seem to get the QAM-256 streams on the DVB side...it won't scan
in the NTSC channels either as DVB or V4L.


Mike  - you say you have both sets of channels...how do you have it
configured in Mythtv-setup to do this...?

Thanks...

Bob
