Got some video files that are in MSS2 using WMAS ( am guessing thats WMV 9 ) is there a way to batch convert them ?

Not sure if rabbie burns already asked this or not ?

Ive searched on the usual sites but am struggling a little bit on OS X but can boot into windows xp pro either using boot camp or in vmware fusion ( virtual machine )

Any help either on OS X or on a windows platform to convert these video files with both video and audio on each video file in a batch preferably as I don't fancy sitting here doing one at a time.
