So if you're a TV nut, this will likely be a good purchase for you. I have Slingbox AV, hooked up to DirecTV on my spare bedroom receiver. It's great, and I watch anything I want, where I want from my Palm Centro cell phone using the Slingbox mobile player. You can change channels remotely, switch between RCA input/S-Video input devices. It has a built-in optimizer function that tries to manage the quality of the stream vs. how much "speed" your internet connection has, but I tend to turn that off for highest quality.
