I use mplayer. The default package (from http://www.mplayerhq.hu/design7/dload.html
) has the required codecs to play .wmv. Install the main source package and the codecs and give it a shot.
Hope you are familiar with compiling it (pretty straight forward if you have a stable system)
But if you do want to stick to rpm's (am on deb) picking the highest version is the best bet.
That said, I think .wmv includes quite a few variants. From my experience Mplayer does support most (all?).
