I have followed the instructions in this tutorial carefully, utilizing the "tweaked" version of disabling services. All 4 WMC services are disabled and withing msconfig the "ehome" auto-start is disabled. Even with all of this windows media center still auto-starts when a dvd is inserted. What is the next option short of installing a different os? --thanks

Hello, and thanks for replying. I am backing up my children's movies so some from pixar, dreamworks, etc. are what I am utilizing. Yes, autoplay is disabled on all counts and my most recent expedition within found a box to uncheck that allowed access to the program within "set program access and computer defaults". I disabled this and upon reboot it did not autoplay but recieved a box that said windows could not open this media; I hit the "ok" button. Now I am seeking how to disable this notification as it is a constant reminder how much I hate windows trying to control everything!

no, I looked for something of the sorts similar to the security notifications but found nothing. On the box that pops up it only has the "OK" button on it.
