OK I’ve checked the broadcast today and there is some good news:

The onscreen logo is in the black bar on the left, so aside from a few seconds where it “morphs” at the start, the presentation is logo free.
The panning shots seem smooth both on the filmed sequences and the space sequences, although a know they can vary. I would imagine a straight slow down to 23.976 would work out OK.

Now the downside - the image is still quite soft (not that I’d expect much else given it’s an upscale) and it would mean a LOT more work if you were to use it as a source instead of the DVDs.

I can capture an episode for test purposes but it won’t be a lossless capture. I have a Hauppauge HD-PVR2 which is not bad but does show a deterioration in image quality when you look for it.

Here is a photo I took from the TV (which is even worse as a test case really as my TV isn’t brilliant anyway!)

Let me know if you want me to do a test capture (I don’t mind either way) but ideally if you’re going for this as a source for the project, you (we) should try to find someone who can do a direct capture of the broadcast stream.
