You want to go DIRECT from a SMPTE hardware device to Windows Media only? I dont know how you normally work and your level of experience and if you are looking for a freakish kind of thing on purpose or if you are missing an easier way to do it?
Pardon me if I am presumptuous, its not my intent; but usually I am working inside a DAW (I use Digital Performer or Cubase). The DAW will have a means to import a video or lock to an external SMPTE lock or sync to a Firewire device (like a DV machine). So usually I get the video, and if its Windows Media, first thing I do is (usually) convert it to quicktime with a codec that is good for working with my system (a lot of trial and error has left me using a few self created presets), then I import it to my project in my DAW, and then line up the beginning of the video with the timeline according to the timecode given.
If this is all real obvious to you, then can you explain why you would need to sync an external SMPTE to Windows Media directly? What are you trying to accomplish?
