Just an update, the HD Homerun still kicks butt, I have even managed to lock in a "sweet spot" in my antenna rotation that gets me all the channels on all tuners nearly all the time
.
I am a little sad now though, after all this work & stress getting everything perfected, Netflix sent me a disk for my WII & now I hardly ever even turn on the media center computer (which is now W7 too BTW) except to watch a DVD. Netflix rocks.
