Help needed (color correction, image enhancement)

I'm trying to recreate the movie trailer for ESB in fullHD. So I looked through the trailers from the official 2004 DVD and found a TV-Spot that had the space/explosion/Vader helmet without the title on it. So I need to resize it to 1920 x 1080 and then crop it to 1920 x 816. I know, it would not look as sharp as the rest of the trailer, but I am trying to get the best out of the sources I have.

I also want to color-correct it, so the space is really black again and the stars are white (or almost white). And all that without loosing the details of Vader's helmet. There's also a lot of noise in it.

What software do you recommend for the color-correction, denoising and enhancement? Is that even possible? Are there any tutorials? Anyone else how did something like that (upscaling a dvd movie to fullHD?) and has some hints for me?

Here's a pic of the scene I'm talking about:

Thank you.

I used avisynth as a frameserver for virtualdub, but it didn't work for me. Frames were skipped or jumped back and forth, of a 2 minute movie only 30 seconds were shown in vdub, and many other glitches.

Any alternatives to avisynth, or at least a hint which filters I need, which program to use the script with, how to avoid the glitches I mentioned above?

Another question:

The sequence starts with this image:

Then comes the explosion:

Then Vader's helmet enters the stage:

It ends with the picture in my first post:

Is there a program in which I can mark the stars in the first picture, and then the program edits out the stars in all the other pictures of the clip by interpolating pixels from around the stars? That way I could use my own background (since I realized that the background is the same as in the opening crawl of ESB, just a little disorted)...

you know I'm probably the last guy you should ask, but I have done some fiddling w/ virtualdub among other programs, and I think that maybe a delogo type approach might work here. logos are often translucent down in the corner and if you do it right you can 'subtract' them from the frame giving a pretty decent result. I think the stars when behind the helmet are sort of like a logo if you think of them being on top instead.

it will take some work but I think you could do it successfully. at least maybe this will get some of the gurus here to chime in a bit...
