What would be nice especially with the early ones if they rescanned the films to 4k resolution, talking to the cameraman Pat O'Shea said the info on the film compared to what went out on TV and video is much better, this is what they do with old movie and re release them on Blue Ray, I have the original Railway children in 4k and that makes HD quality really lacking.
The thing to watch with sky is they don't not stream anywhere near the full bit rate, otherwise it would cost them a lot more money to do this, data is money when they transmit, the only stuff that generally went out full bitrate on sky was main BBC channels and probably ITV now, but of course the BBC don't mind spending people's money.
If you are downloading these I would like to know the file size please,as if they are downloaded it could be a much higher bit rate
