We do this ourselves. You need to connect your computer to your TV. If your TV has a computer input then you literally just plug your computer into your TV as if the TV was a "monitor". We did have to buy a cable to do this, I want to say it was around $30. My hubby wasn't able to get the sound from the TV (he's not very technically savvy, I am sure there is a way to do it). So we have the sound through computer speakers. You'll need to get a wireless router if you have more than one computer and you want one dedicated to just the TV (we had an old computer that had a fried power supply, we replaced it and it is hooked up to our living room TV). You can then access TV on any number of websites (hulu.com, justintv.com to name a few). We've never had cable, but we bought a new TV and decided since we had the extra computer we might as well hook it up, we love it.
