I've been annoyed at the fact that you couldn't apply playlists to video clips (music videos in my case), so I created a simple app in VB.NET to create wvx playlists for MCE.
Just remember to save the wvx file within the path for "My Videos" within MCE.
Personally I have created a Playlist directory where I keep my wvx files.
Then just navigate through My Videos in MCE to the playlist file.
I know it's not within the MCE interface but maybe I'll tackle that in a few months when I get some more time. But hey, it's FREEWARE and it works!
