Improving DV to HD music video reformat.

I would like to have this music video of mine reformated from DV to HD. Not just the resizing--I could do that, but filters and/or other "tricks" you may have up your sleeve. Just want it to look as close to as if it had been shot in HD as possible. Approaches and/or samples will be getting my attention. Color improvement (semi-professional to professional look) would be a definite plus. I'd be providing the original DV file and a master WAV file. Here's a YouTube preview though: [login to view URL] Thanks to all!
