Welcome to the forum,
BD has a lot of teething problems and all of the problems posted in this thread have occured to me also. It IS copyright protection and it is the sensitivity to pausing due to the fine beam used to pick up 48 gigs of data crammed in. The only way to keep it going is the following procedure:
If you have a HD Tv or Projector make sure you
A. plug in the HD cable
B. right click the desktop and click NVIDIA Panel and disable NVIDIA control panels default detection of a 'Duel' screen setting and set 'Single screen'.
C. Then Go into Vista's or XP's 'Display Settings' by right clicking on the desktop (Personalise).
D. Generally as a rule for smoother troublefree play set the monitor '2' in Settings to the resolution of the monitor like 720p or 1080p, you can, but don't upscale to use 1080i on a 720p monitor.
E. Click the 'This is the main monitor' for the '2' monitor after 'attached' is active.
F: Start the WinDVD BD either in Media center or on its own and go full screen pushing 'Z'
G: If you play a Blu Ray movie NEVER pause it let it play on and return to the place you were if you are disturbed when watching. If you stick to this system you won't disturb the delicate balance BD insists on to work, because if it stuffs up you WILL have to reformat and I hear Cyberlink BD player doesn't play smoothy.
H: After the movie, bring up the display settings and return the monitors back to default '1' (This is my main monitor) as the copyright protection is more enforced with blu ray so as not to be used in a public display capacity one monitor at a time. Clarity I assume. Anyway I have not had a problem since I reformated to get rid of the out of the box factory settings which are never very good. Never try and set up the BD after starting the movie...it will not work again unless you reformat. Set up to play then play.
