BTW, the Lunar I played (and beat) was an original. It never froze, crashed or hanged on my model 2. It also player Jurassic Park perfectly (again an original, from the time when I could still find SCD games fo rent).
Maybe it is indeed a matter of how the ripping is done. I have a burn of Lunar SS that hangs on my CDX when Ramus appears. It get's past the logo just fine, and I'm sure the problem is due a few extra gaps between some audio tracks that shouldn't be there (I noticed that after burning the game, but I haven't burned it again).
Jurassic Park is supposed to have longer load times on a CDX: the game is not "incompatible".
