I'm in the same situation as you... I put a digital ant. on my roof, I have all the networks dialed in, Fox is a little jumpy but not too bad. I used good maps to find the ant. for the stations and pick up the best signals.
Tried to watch it on the site but video quality was bad, commercial breaks where 6-7 long and they only played 5 diff commercials in the 30mins I watched. So not worth the trouble for me.
