I really like TVU and if the game was on CBS, it would be the answer. It is difficult to find an ABC stream online.
Still, I would download TVU
My wife and I are talking about the possibility of moving to Korea and teaching after we graduate (my knee may prevent me from going chaplaincy), so I have done a lot of research on alternative TV reception. Slingbox is your best bet, but you already there. If we go, we are going to put a slingbox in my mother in law's house. I have an old laptop that will work nicely as a slingbox receiver. It has SVGA out and could be used as a dedicated tv receiver.
My left knee is in not-so-good shape from carrying too much weight for so long. I have lost 115 pounds since August of last year, but the damage is done and I don't know that there is enough glucosamine/condrointin in the world to fix it. Knee replacement surgery is not generally done for people under 50, so I may just be out of luck.
