Bother - I was going to suggest trying to run fanpass from the mac to the TV and see how that fares. (I had originally read that as "mac mini")
I'll see if I can get fanpass going on my samsung TV and compare it against the appletv. I've had much, much, much more success with the appletv than any of the built in apps for "smart" tv's.
Will report back later tonight whether I see any significant difference.
