IWMPDVD.isAvailable (VB and C#)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The isAvailable property (the get_isAvailable method in C#) gets a value that indicates whether a specified type of information is available or a specified action can be performed.

Remarks
The DVD features of Windows Media Player will not work on computers that do not have a DVD decoder installed. You can determine whether a decoder is available by calling the isAvailable property (the get_isAvailable method in C#) and passing in the System.String value "dvdDecoder".
Every DVD is authored differently. The methods available during DVD playback and navigation depend on how the DVD is authored.
