Glad you got it going Sean.
Are you running Camelot Beta? If so, what do you think of the new skin?
I have some questions about wake on usb.
I have never used it before, and am a little confused about what it can and cant do. I usually just leave the Revo running all the time. I am using a Harmony to control it (I also have a Dinovo Mini set up with it). So what do you do to wake from USB? Do you use a mouse to wake it, and then use your remote for control?
Im not sure about your MPC-HC audio issues, but it looks like dsplayer may be ready to use for windows xp users. Might be worth looking into.
BTW, I also did the same as you...uninstalled mcafee and threw avast on there. Its the antivirus software I always recommend.
