I recently discovered, quite by accident, that DVD2OneX will pause its processing if you put the Mac to sleep! This may be old news to some people, but until these last few weeks I had virtually never put my laptop to sleep before, so discovering this was a real bonus. I've been wishing the program had this ability every since I started using it! That said, the ability to pause processing without sleeping (so the user can do something else in another CPU intensive program) would still be useful!
