Has anyone hooked up a DISH HD box and run it through Window Media Center that comes with Vista Home Premium? I rigged up cable through a HP m9250f machine with no problems. I just cannot seem to get the same results with the same PC and a DISH VIP722 box. I go thru the set up on WMC and the machine sees DISH but will not let me complete the setup because it does not see any IR cables. The problem is there are no IR cables on the DISH box.
