Dod you need to access the dvd-video from a computer, or do you only need to dispaly/link to ROM content? If the latter, can’t you build a stand-alone program (executable) that runs right from the disc, using Flash or Director? (the latter can also access the DVD-video, but it’s quite buggy in that regard). We build stand-alone DVD-ROM presentaions all the time that require no installation on the user’s computer, and have embedded PDFs, powerpoints, etc.
