Right now we have a 'media computer' hooked up to our HDTV. This is not a Media Center Edition pc however. We're just running XP home. I am thinking of upgrading to Vista on just our media computer. I know that Vista is/has MCE. I know that MCE can work with a remote. Here's my question: Our current computer clearly doesn't have an IR receiver so how does upgrading to Vista and using a Remote (harmony 880, to be purchased today) work? Will I have to purchase an add on IR Receiver? Or is it just impossible to use a remote with my existing rig? Thanks in advance for any answers.
