I've currently got an 'almost' perfect setup, using xinerama I have mythtv running on my second display (a tv) leaving the computer monitor free to work on. I also use a remote.

Only thing is, whilst working on my computer monitor, if I then go into the program guide using the remote, I can move one space in any direction, but after this the direction buttons stop doing anything, although I can still go back etc.. it's seemingly just the direction buttons behaving in this manner.The only way to get them to work again is to move the mouse cursor onto the tv screen and click on the mythtv application.

Is there a way to work around this? If not directly I'd be happy enough if it were possible to use a script or some such that can be assigned to a button that once pressed will pass focus to mythtv.

Thanks in advance!
