Whether Windows Media player supports DVD playback

Q: Why did you just buy the IBM T43 installed Windows Media Player, after clicking the tools → options menu, you can see the presence of the DVD tab in the Options window that pops up, and the same version of Windows Media that is installed on your desktop There is no DVD tab in the player?

Whether A:windows Media Player supports DVD playback depends on whether there is a supported decoder (hardware or software) and a supported DVD drive. If these conditions are available, Windows Media player provides DVD features and configuration options in the user interface. Because DVD drives are already standard in T43, there is a natural presence of a DVD tab in WMP. On the desktop, if you do not have a DVD drive and the compatible decoder is not installed correctly, you do not see the DVD tab.
