I have received a Virgin 360 Box today but I cannot get it to work with my Harmony Ultimate One. It's asking for a model number and the only thing I can find that looks like one is on the underneath of the 360 box - DCX960 but it just won't turn on in my Watch TV activity. I'm sure I've set everything right, the TV and amp come on but the 360 box won't! I've been messing with this thing for almost 4 hours now trying to get it sorted, I'm ready to smash the thing up with a hammer! Help!!!!
