Problem playing video tracks

[Skybird]

I love the new features on 3.310, but .wmv files will not show on a second display. When I click "Add Video", it defaults to .dat and .vob files. So, I change the "file type" to .wmv and it will add to the Playlist, but the video only displays in a second window on my laptop. When I go back to adding .kma files it automatically displays on the second display. Is there something special that needs to be done in order to view the other file types and a second display that this new version is supposed to support?
