Page "DVR-MS" Paragraph 3

Although it is not possible to edit unprotected DVR-MS files through older software programs such as Windows Movie Maker for Windows XP, the files can be edited using Windows Movie Maker for Microsoft Windows Vista or Sonic MyDVD.

A simple registry tweak / hack also exists for allowing the Windows XP version of Windows Movie Maker to natively import / edit DVR-MS files.

Some early freeware applications which convert the files can be found from third parties such as at The Green Button.

Microsoft's Developer Network ( MSDN ) has an article with sample code and binaries demonstrating how to use DVR-MS and convert them to WMV.

Also, Windows Media Player 10 shipped with a transcoder to convert DVR-MS to WMV only when syncing with portable devices such as a Portable Media Center.
