I like the flexibility of watching videos on my iPod on a TV. Watching a video on the tiny screen is just about impossible for me, and I like to watch fitness videos in my home gym in the spare room. But I don't see any reason to invest in Apple TV. This is how I do it.
First of all, you will need to load some videos on your iPod. My post on how to get free video podcasts at iTunes is here. Once you have done that, all you need to do is to get a simple Apple Component AV cable, which you can order online or get at an Apple store. It's just a dock that connects to the AV cables in any television. No, you won't get high definition this way. But I don't care about high definition here, I just want the convenience of being able to watch the videos in my workout room.
By the way, the silver thing that the iPod dock is sitting on is a combination DVD/VCR player. I don't use that much any more.
