I'm also really interested in getting Remote Buddy to work flawlessly with XBMC. So far it pretty much doesn't work at all as far as I can tell, with the Remote Buddy menus flickering / only displaying briefly as they change. I'm putting this down to the very early stage that XBMC is currently in but it may be something that can be sorted out?

Is XBMC doing something graphically that conflicts with Remote Buddy?

I'm also really interested in getting XBMC and EyeTV to co-exist peacefully, with a reliable method of switching between the two using the remote.

Anyone who has had any luck with this or wants to collaborate together, please drop me a line!

Cheers, 
Ed
