Enabling AutoPlay for a DVD Movie
In Windows 7, the settings to control AutoPlay are conveniently located in the same place for all media types. To change AutoPlay settings, first click on the Windows start button (the orb) and navigate to Control Panel. Next, click Hardware and Sound and then AutoPlay.
Listed in the AutoPlay settings window are a number of options and controls for various types of media that can be inserted into your computer. For a DVD, Windows can take a number of actions depending upon your own preference. Additionally, those actions can vary depending upon what type of DVD has been inserted and what media is prevalent on the DVD. By default, Windows 7 will alert you that removable media, such as a DVD, has been attached and the current options that are available.
Assuming you wanted to automatically open Windows Media Player and play the movie whenever you inserted a DVD movie disc, you could click on the down arrow next to the DVD movie label and choose Play DVD movie using Windows Media Player. If you have other media players installed, they will likely appear here as well.
Note: If "Use Autoplay for all media and devices" is not ticked at the top of the AutoPlay settings Window, then the AutoPlay window will not appear for media types that do not have an action specified (other than "Take no action" or "Choose a default").
