I have made this argument before, but I might as well make it again.
I would love to see a new version of B5 that had its fully CG and comped shots redone. Not because I think the old version is bad; I think it is iconic and historically significant, and in fact I would actually like to see an extra containing the original uncropped version of that CG work if they should publish a new edition. No, I would like to see a new version because, in a sense, they already "messed" with it for the version we have now. And I would like to see some of the problems that created undone. Due to the original 'resolution independent' CG files being missing, the CG space scenes and the comped scenes had to be cropped from the old television broadcast, which was done at 480 lines, interlaced, and with an inferior telecine that picked up less detail.
Now, I actually love the way the widescreen elements of the DVDs look, and since it was originally intended to be that way, the "messed" above is in quotation marks. But one element that would've factored into that original vision, files capable of rendering the CG and comped shots wide or in any other resolution, are now missing. I'd be perfectly happy if they'd remade those for a proper SD release, looking exactly like the old ones, only not cropped this time.
But that isn't going to happen. What may happen is an HD version, and they really would need to redo the comped and CG shots for that. This would make me very happy. To me the space shots look all right as far as framing goes, though the cropping does make them look rather blurry. However, the scenes that have 16:9 shots mixed with comped 4:3 shots cropped to 16:9 of the same scene look really jarring to me. You can see how much is lost, and how big the difference in framing can be,
here. Look at the screenshots provided for the How Much Quality Do We Lose For Composites section.
In addition, I would love to see the original film elements in a higher resolution, and with a better telecine and some work done on cleaning them up. There is a lot of noise and grain and dirt marks on the wide telecine we have now, and the technical means to clean those up exist. Instead they didn't even do some de-interlacing for the shots that required it, so a new version that had some attention payed to that would be really nice.
Finally, I wouldn't mind a new mix for the sound. What we have on the DVDs is a 5.1 surround mix with dedicated channels, but from what I understand all they really did was take the matrixed channel from the pro-logic mix and throw it on the back channels, and take the voice track and throw it on the center channel. I wouldn't mind a new mix that added some directionality, and used the dedicated channels more.
