Do you use Apple's Remote -or- some other remote to access Front Row and other applications?
I use Griffin's AirClick USB with my OSx86 mPC.
Griffin's AirClick USB is a remote control for Windows and Macintosh. This is a great alternative for people with Mac's that did not come with Apple's Remote. I had to download Universal Driver from Griffin's Website to get the Front Row functionality. The remote also works with Apple's DVD Player. I have not tried the remote with Windows. The keys get stuck at times but the range is fairly good using RF Frequency (instead of Infrared).
I picked up one for around $30 on sale at local CompUSA Store here in California, USA. You can also find at NewEgg.com online.
