I can't get WMP to play Mpeg-2 DVD files or view the files when selecting scenes (for the menu) in Ulead MovieFactory when authoring DVD. Mpeg-2 SVCD works fine with both WMP and UMF.

The DVDfiles can be seen as thumbnails when I'm exploring the drive (WMP) and in UMF when added to UMF. Since the files can be played using PowerDVD I'm not that concerned that the files can't be played using WMP but it's quite annoying not being able to scan the files in UMF when selecting scenes for the menu. I guess that I'm missing a codec but I can't figure out which codec or where to get it.
