I put togther a quick video (with no sound) to show how the setup works. If I could get the EyeTV features fixed up, this would be a nice solution for what I want to do. At this point I am likely to buy a newer Mac Mini next time they are revised, likely with Leopard, and use my existing one for a CarPC project.

I did find a good antenna position to pick up all the local HD stations except Fox with good quality, so when Heroes returns, I should be set to record it.
