I'm not sure where to put this, so hopefully there are some media center pc users here. For Christmas I'm looking into getting my father a logitech harmony remote to control his media center pc (running winxp and the software that came with his tuner card), directtv pvr, dvd, and stero. I just don't know, which remotes will control the media functions of a PC? I know the 680, 880, and 890 can, but what about any others? Any thoughts on this or information is greatly appreciated.
