Hi Mark —

Not sure if this would help at all, especially since your post is over a year old now! Nonetheless: My company Limeboy Sofware has released Timecode Commander, which allows you to burn timecode directly into WMV files.

You can download a free trial to see if it would solve your problem.

Kind regards,
Mike.
