One of our long time windows media fan, Mido asked us about this.
Can you teach me how to covert DVD to WMV in Vista64? The old conversion guide is not work now.
My initial impression is that Zarax's DVD to WMV guide in his homepage should work under Windows Vista x64 editions without any issues because, Windows Media Encoder 9 that is primarily in use in that guide is Windows Vista x64 compatible. There is Windows Media Encoder 9 Series x64 Edition from Microsoft that Mido should be aware of.
Complexities could occur in my DVD to WMV guide with AviSynth. I know for a fact that it works under Windows Vista 32-bit editions. As I don't have a 64-bit capable CPU I am not able to test this guide on Vista x64. Time to do some research...
