adding wmv files to the playlist?
 

is it possible?

I know I can open one wmv file by switching the "media files" to "all files" in the open window, but that option isn't there when adding files to the playlist.

in the 'file name' textbox, type *.* [or in your case, *.wmv would be alrighty] then hit enter. Every file will be shown

the playlist also supports drag&drop from windows explorer ;)
