After registering - grey-out or remove register option under menus. I have seen a hundred Blu-Ray disks & STILL haven't seen the files this program is looking for to start - SO - why not let the program be started when the disk is inserted - THAT - would be helpful & stop a lot hair-pulling when trying to use this program. I have tried it on a couple of DVD's & it seemed to do the job - (still have a hard time with all the crap about 3D - wake me up when 4D or maybe 5D is available).
