mythhdhrrecorder only supports tuning by virtual channel number.  Your
Hauppauge WinTV almost certainly only supports tuning by
frequency/program tuning so it can't share the same videosource with
mythhdhrrecorder.  The internal, HDHR recorder supports both virtual
channel number and frequency/program tuning so it can share the same
videosource with your Hauppauge WinTV.
