The only way digitally, you mean? Because you can still buy physical DVD's and Blu-Ray's, right?
This is one of the problems with copyright laws - creeping scope to make normal sensible actions illegal. Why is it illegal for me to modify my DVD player to play a DVD I've had to import (at great personal expense) and that is not available (and probably won't ever be available) in my region?
There's a bunch of these.
