I have actually worn out my first set of FF DVDs

Wow! (I have yet to buy a set, I know I will watch them constantly when I do.)

The Equalizer DVDs... no idea; some bias against releasing shows starring Edward Woodward? << insert my Callan grouch here! >>

I can't help you on The New Professionals either, I'm afraid (I never watched it). The forums at The Mausoleum Club are my usual source for finding out what archive material is up for release.
