CW said:don't know if you are aware but you can get 1080p versions of their titles from pearl and deans shop for £2.99
Doesnt seem to be a direct link so here: http://www.pearlanddean.com/?node_id=1.32
Thanks! I looked at that page before, but didn't notice that there were also options to download the older versions. I now have the 70s/80s version, converted to resplendent 16:9 PAL.
Regarding Dolby/DTS/THX logos, I was personally after the older stuff but I do happen to have a couple of discs of more recent idents (commercially manufactured, not entirely sure who for) - I can list the contents if there's interest for other projects.
