I think this issue is specific to using the Blackbox external recorder, 
mythhdhrrecorder. I went back and add the HDHR as HDHR tuners and just 
created Input Connections for these tuners using the existing SD video 
source and it worked fine.

So I guess if I want to use the mythhdhrrecorder for it's TCP/IP usage 
of the HDHR, then I'll have to rebuild from the ground up and define one 
video source for the tuners on mythhdhrrecorder and one for the 
hauppauge WinTV quad.

Which I will not do, so I'll stuck the what I have.
