Q: What kind of TV tuner do I need to watch TV in windows media center on dell dimension 5150 ?
A: The ATI TV Wonder Elite was given the best rating by CNET. http://reviews.cnet.com/4520-9332_7-6381535-1.html All you need is a free PCI slot (you should have at least one). Edit: Just checked and that's an old model. Their new products are here: http://ati.amd.com/products/atitvwonder.html
