I was actually curious why slysoft requires a driver where MakeMKV doesnt. Also, why AnyDVD couldnt update the the driver dynamically; keeping protection information hotplugable; or move the protection into the app itself instead of a driver.
Anydvd only needs to reboot when the driver is updated. Otherwise it does not. It tries to be smart and warn you if it thinks a reboot might be required.
