Mike, I just bought this, the entire NFL schedule, streamed online in HD:

I car put the games on my HD projector or other TV connected to my 'puter.
Just requires a decent 'puter and a minimum 750k download connection.
Additionally, there are several folks who stream the games online. Sometimes the quality is suspect, which is why I went with the NFL route. Ther have a demo on the link above, and guarantee the live quality is equal or better. Not bad at all...
You can also watch games from their archive during the season. A tad more expensive, but worth it, IMO.
