I have a question for those familiar with the x1900 xt in the mac-pro. Is it possible to use the S-Video in addition to doing screen spanning with two monitors? I have two 20" ACDs that I want to hook up the two DVI ports in spanned mode, and then a TV I want to hook up via s-video for movies, etc. Can you do all this at once? What's the interface like? Does the Tv just show up as a third monitor in display preferences? Thanks in advance.
