Many if not most of the Internet TV offers are scams from thieves so don't go there.
Here, because of a gaffe by the local cable company my installer could not connect the TVs. So I set up the phone and internet and sent them on their way.
FOUR MONTHS later and here's what we do now.
1. OTA HD. We added a few HD ANTENNA's for what is called OTA (over the air) and that gets us about a dozen channels.
2. ROKU. See http://news.cnet.com/8301-17938_105-20024488-1.html
Update. I think I want an Apple TV to replace this.
3. You have the Wii so try it's offerings.
I have a DSL connection, a Wii and a hdmi ready tv. I don't want to buy a lot of gear.
