Since you needed it tomorrow, and tomorrow is today, then you probably missed your deadline.
You still might just be spinning your wheels with Forty-Two DVD VX Plus. If you look at the reviews at
http://www.macupdate.com/info.php/id/12150 it doesn't look very promising. Hopefully, you will have better luck than the reviewers.
Just because the author makes a claim that an application performs certain tasks, doesn't make it so. If you're willing to take the chance and pay $15 for a "maybe", go for it.
Just "maybe" they have corrected the problems. Personally, I would keep my money and look for the pc application. I still don't think that there is an application that converts what you want on the Mac side. But then again, there may be other authors that make the claim and come through.
I would be very interested to know if there are users that have successfully used this app to convert .wmv files (preferable on multiple occasions).
