[mythtv-users] adding HDHR to system

[Jim Abernathy]

Last project was eliminating my HDHR Quatro and replacing it with a 
Hauppauge WinTV Quad.

That is complete and I'm using XMLTV sdjson_sqlite grabber.  At this 
point I'm stable, but on occasions I'm recording on all 4 channels of 
the WinTV and thought about adding the Quatro back for Live TV only.

I can use the HDHomerun Viewer to watch live tv on the Quatro, but it's 
not integrated with Mythtv.

So my question is can I add the Quatro back into mythtv using the 
Blackbox external recorder, mythhdhrrecorder, and still use my exiting 
EPG database I setup for the WinTV using tv_grab_zz_sdjson_sqlite. I 
don't want to screw up my exiting recordings or pending recordings. Can 
I setup the mythtvhdhrrecorder to use my existing SD XMLTV source or do 
I have to have a new video source just for the mythhdhrrecorder???
