The PC codes in CCP work just fine. No problems.
There is one problem though, you need to have a media center edition of windows to PnP the USB IR receiver. If you don't have MCE of your windows version you need to change the irbus.inf file to get everything working.
Lots of documentation on the internet about this.[Link: it.megocollector.com]
If you have problems with controlling it via Hauppauge CCP codes... assume the PC the culprit until you have tested it with a stand alone MCE remote.
It will work, it just takes some tinkering on some installs.
