It stands for Remote Control Device AFAIK and it's a bug in Tiger/Front Row that makes it hang. Hopefully Apple will issue an update to fix it sometime soon. In the meantime, you should be able to Force Quit it without any hitches. Just out of interest, does it ever work for you (the process and the remote)?
What do you mean has the process and the remote ever worked for me? I haven't forced quit it yet and I'm running Front Row fine if thats what you mean.
Thanks again madjew, you seem to be anwsering all my questions tonight!
