I have a Harmony 659 I use in the bedroom for a Sony 34" xbr, 921, and DVD. I just purchased a Harmony 880 for the Family room to operate a Sony 60" Grand Wega III, a Onkyo TX-602, a 921, a Samsung DVD Recorder, an XBOX, and an old VCR. Went on the web and listed the equipment and TV input and Receiver inputs and it worked just as advertised. I did have to remove the UHF antennae from one of the 921's, since they only seemed to accept an IR signal on address 1. May be a better way to do it but I haven't had time to experiment, and everything operates fine from the default 880 setup.
