The way you can do this today is by installing the tuners in a home theater PC and using Media Center Extenders (such as an Xbox 360) to access the HTPC. However, if you think Windows Home Server should support tuners, you may want to submit a product suggestion on

And I have to admit that I disagree watching live TV would be "great" on a laptop. It might make it up to "bearable". :)
