By the time of Studio321's demise, Most DXC, Express, and Platinum users had "upgraded" to the "ripper-free" versions (321's vain legal ploy to attempt to spare it's product from judicial execution).
If you are running one of the older "ripper" versions, you don't need anyDVD and it indeed might (you seem sure of it) cause the conflict (the freeze you spoke of) to have two similar functions running at the same time.
After you shut off AnyDVD, check, in Windows "Services", to see if any AnyDVD services are still running. Select "Stop" the Service for your present windows session or select "Manual" to activate the Service when needed for all future Windows sessions. Also try unchecking AnyDVD's "Load at Startup" command and then reboot. Thereafter just turn it on when you need it for other programs.
If that's not a fix, then it's probably regedit time. and I learned never to advise anyone in that area.
