How to play a DVD?

How do you play a DVD on the Windows version of XBMC? I added the usepcdvdrom entry to my advancedsettings.xml file, however, the little yellow icon in the bottom right corner doesn't appear (like it does on the Xbox version when you add this entry). If I add the drive as a source all I get is the directory listing (vob files, etc.). Is there currently a way to just hit that little play icon in the bottom right and have the DVD play? Btw, I'm using the latest build 12767.

Thanks,
Harry

if I remember everything right dvds aren't supported in it. You might want to check the changelog and see whats working in the windows build
