Should just plug and play if the connection is good. From what I've read around the forums you shouldn't press the F1 key for OS X. Instead, download a program called MirrorDisplays and open it when you've connected your 10v to tv. This will turn OFF mirroring (showing the same image on both screens) and enable extended display (having the tv as an extension of your 10v screen). Make your tv the primary extended display and you're good to go for watching movies. I haven't tried any of this yet since I'm still waiting on my DVI cable, but that's the jist I get from other forums.
