Ok, I'm talking Intel here, so you'll have to take the relative
performance capabilities of different architectures into account, but...
For software DVD playback, with a single-tasking OS, you need 200MHz+, and
decode times may exceed the time available if the image is particularly
complex, or has a lot of movement.
For a multitasking OS, add 50MHz at least.
It won't likely be coming to a QL near you anytime soon.
