You sure about Look Around You 2 as quality goes? The symbol in the episode intro continuity is as good as I've ever seen. The edges aren't smooth, but I was under the impression that's how the computer drew it.
I've viewed other examples of similar quality, but nothing better. When it's a tape recording off analogue, the colour can be a bit variable - for example, the double stripes appearing more red-orange than the tan-orange seen here and on the DVD. I would assume they used a better source than a domestic format for the episodes?
Well, the LAY2 copy has a stripey pattern pulsing over the orange bars for a start, so getting the right colour out of that isn't easy. Getting the gradient right on the 2 itself is always going to be tricky too, as it would be with any gradient. It's a very sharp picture in comparison to VHS for example, but it's still a bit blurry and so it's still not easy to trace it perfectly. I wanted to get the exact shape of the fat pixels out of it, but you can't. A similar effect is possible by putting Flash Player into low quality mode, but it's not the same
I'd like to see a bitmap dump of each frame from the memory, but that'll never happen unless the hardware still exists, still works and somebody the gear to do the dumping. Creating a new widescreen digital version from that would be a piece of cake, you'd just add the extra frames for the extra length of the lines and have the original frames sandwiched in between.
One thing though, the NTNOCN DVD helped to show that the top line on the clock has a darker shadow than the bottom line...

...which I could never tell from a VHS.
