Agreed. However I don't want to use my HD cards whenever possible as
the resulting file size is about 7 GB per hour. My PVR-250 only uses
about 2.2 GB per hour and the quality is sufficient for me. Thus I want
to use the HD tuners only if the show is actually broadcast in HD.
Configuring the PVR-250 card first, leaving the tuner inputs equal, and
giving a higher priority to shows with the HD flag set creates this
