It's not that hard. Look at a DVD title. Is it non-anamorphic? Stereo sound? Is there a pre-existing laserdisc? If so, you've probably got a laserdisc port. Looking at my DVD collection, there is one that I know is an LD port (Criterion Silence of the Lambs), and another that I suspect is a port based on my criteria (1st edition Star Trek Generations).
