After installing the 64bit version I tried my Leadtek DVB-t stick. Leadtek says on their website that this item will be taken out of theit products. But what a surprise, after inserting the stick the 64-bit driver was installed without any problem. I started the Media Center and after a sender search I could watch TV!
In Vista this didnot work that great. You can say what you want about Windows 7 but I never was happier with my XPS 1330!!!
