What you are running into isn't AutoRun, or AutoPlay. It's the 'default action' for double clicking on a DVD, which is "Play". If you right-click the drive (with a DVD in it), you'll see "Play" is highlighted.
If you would prefer it to "Open" the DVD as a folder instead of playing the movie when you double-click the drive, then you could try editing the registry and change the action for the "DVD" class:
- Open
regedit.exe.
- Navigate to
HKEY_CLASSES_ROOT\DVD\shell
- Change the "Default" value data from "Play" to "Open" (without quotes).
I believe the change should take effect immediately, but I'm not 100% sure, as I don't have a DVD disc around to test with right now. :)
1Yep, that did it. Took effect immediately, no reboot needed. – Joe Schmoe – 2011-09-05T21:01:54.057
