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