BleepingComputer.com: Hulu on Laptop so it Shows on TV - Issues

Hi everyone,
I have a MacBook and I am using a Mini DVI cable to hookup the laptop to my TV so that I can watch Hulu, Netflix, etc. When I try to watch something from Hulu on my TV I can't get the image to be centered. When I plug in the Mini DVI cable it refreshes the image on the laptop screen so that it's blown out on the laptop, but is a normal size for the TV, but it's off centered on the TV because it's blown out on the computer screen. I hope that makes sense. Anyway, how do I fix this? I tried using this for a iPhoto slide show and that worked fine, so I'm not sure what's going on. Thanks for any tips or info!!
