I'm the originator of this thread, and I just wanted to close the loop 
and say that my tearing has gone away. I have the same settings as 
mentioned above with the following exceptions:
* HDHomeRun
* OpenGL vSync didn't seem to matter for me
* TripleBuffer didn't seem to matter for me

Bobby mentioned "The VDPAU w/ Advanced 1x deinterlacing" which got me 
remembering that I don't recall being able to adjust the VDPAU playback 
profile anymore, since I went to mythtv .22 with the Avenard patches. I 
looked around and found the various playback profiles... I ended up with 
"VDPAU Normal" which is working great for me.
