Huh. This is in dual X session mode, right? (Meaning no TwinView 
enabled). From the sound of it, another user might actually have 
hardware acceleration on both displays when using TwinView (I've asked 
for confirmation).

I still have to get around to trying it...

Nope. But then I don't do a whole lot of watching live TV anymore. I 
just record stuff, and watch later, once the commercials are flagged. 
The only problem I have is that an occasional recording stops recording 
at a random spot for no apparent reason. I think it is maybe one out of 
every 20 or 30 scheduled recording, but there's no pattern... I've 
recorded 5 hours of back to back programming without problems one day, 
then the next day, a single one-hour recording fails, but the day after 
that, three more consecutive hours record fine. I shouldn't bitch 
though, because I haven't really investigated yet. :)

Too late for that here. But I'm thankful too!
