What I am trying to do is project images on a cyc with cheap projectors, Using one image/video to be displayed on the cyc with two projectors carefully aligned and keystoned.
Will a program such as powerpoint or the open office version of powerpoint spread across the two screens, or can I only asign the slideshow to one output?
Also, any cheap slideshow/presentation programs that work well with video?
Your going to get a hard line enless you get a piece of software/hardware that divides and dithers the image so it can be merged. If you just want a cheap and dirty split, get a cheap nvidia card that has two outputs and set it up to do duelview. Powerpoint 2007 handles video pretty well, keynote does a better job. Otherwise, you question has been answered in the the above posts.
