wmv video with virtualdub

[lbrtnstn]

I wish to insert permanent subtitles on a .wmv video. But VirtualDub can't open these types of file. Can I use other program besides VDub, or configure VDub to accept .wmv videos?
Please answer, it's quite urgent. Thanks :)

Virtualdub-MPEG2 (http://fcchandler.home.comcast.net/stable/)does accept WMV.
