Can a "digital copy" of a DVD from Warner Brothers be converted to Zune software?

I purchased Terminator Salvation on DVD. It also had a sticker/logo on it that there was a "digital copy". The digital copy gives you one version of the movie for your pc and one portable version to be added to a portable device. I was thinking, "Awesome"! But now, I have the movie available in the windows media player, both the pc version and the portable version. I want to get it transferred to my Zune. All the Zune movies that I have downloaded automatically to the WMP, and now I want the WMP movies to transfer to the Zune software. I don't think usage rights are an issue because under properties it says "This file can be played an unlimited number of times. Collaborative play for this file is not allowed. This file cannot be burned. This file can be synchronized once more. (requires a device that can play subscription files) The media usage rights for this file cannot be backed up"
