I'm sitting and watching the third replay of I Should Not Be Alive on the Discovery Channel in Asia. I'm at the Sheraton Walkerhill and they have limited channels. I can't watch network internet tv because they block you if you are outside the us. I tried using a proxy server but it was too slow. I don't want to pay to watch it on Itunes. Anyway made my decision to buy the slingbox when I get home. What are the cons I need to be aware of?
