lol @ ur keyboard punk'in ya. hmm haven't looked at any interference related issues. yes the 890 shoots RF at wireless extender that is sitting 5 feet from the PC, which then reblasts that info out via IR to htpc, xbox, tv, and avr. as of yet, i haven't had any issues from the controller or even it's notoriously bundled software (iMon SoundGraph). up until this point everything is controlled exactly how i like it, with little or no hiccups. i just dug up the xbox's usb receiver. Later when I get a chance i'm going to install the software and try fire up GameEx. I still hope that a lack of a "real" controller is what's making this thing go batty. if that doesn't work - i can try uninstalling GameEx and re-installing so that a controller is present on the system DURING the install. and if THAT doesn't work hang my head in shame and walk away - mumble something about nice concept but just couldn't get it to work.
