Mount a *.dvd rip

Usually I would mount a clonecd ripped file with daemon tools in order to play my game. This however doesn’t seem to work with a dvd game that I have successfully ripped with clonecd and even burned a copy. Any suggestions as to what tool I should use to mount these files.

What game is it and what copy protection does it use? Scan with A-Ray scanner or Protection ID and let us know.
