Hi, I'm new WinMo user here..........

anyone found a free app that could play .RMVB video files?

looking to play TVB drama series on my phone, but TVB is not the main point.....
I admit, P.OoR.N is the main key! LoL 
besides that, a friend of my just transfer me a Blue movie via Bluetooth,
the transfer done, but i can't find the RMVB file.....
that's a bit anoying for me now!

anyone can share me with your experienced?
