I'm having trouble finding information on video cards for mac. It seems that the only two are ATI and Nvidia.. Neither of which have TV out?! The thing is, that my PC has a Nvidia Geforce 4 MX - that allows me to have a line out to my TV - so i can watch a DVD/Divx on the TV, while on the net/homework. Is this sort of thing possible on a mac..? So my monitor displays a desktop while the tv is full screen video (think this is called 'overlays'?)... If so - i'll go all mac baby!
