I use XP home and I have two administrators: myself and my wife. I looked around in the forums and stuff and some of them said it did something funky with my registry. Do you think this is true? I'm not even sure that my cable is working correctly, so I'll try it later and see what happens. BTW, when your JP1 cable is plugged into the remote, should you be able to turn the remote on?. One way, you can turn it on and if I flip it, the unit won't turn on. Anyway, I let me know if I should just go over to Yahoo and post this. I know that's where this type of talk is preferred.
