Media player crashed remote

I was browsing an iMac running Tiger set for ATP and SMB shares.and wandering around and failing to play any files, it started to hang finding content, then the directory appeared and the remote wouldn’t do anything, I obviously thought it was the ATV that had crashed. I pulled the plug and on reboot the remote still didn’t do anything. Each button press registered as two flashes of the White light at the ATV end.
Anyway, I used the Apple remote app from the iPad and unpaired then paired the remote and all was well. Without and iDevice to use I am not sure what I would have done.
