I've been looking into getting myself a Complete Physical Collection of Doctor Who and while everything 11th and Onwords I'll Likely go with Bluray for the Better Quality, I'm not sure about 9-10?

I did Originally Watch Those on TV Back in the Day, Noting that the Quality most Certainly wasn't even near HD. So I can't help but wonder if those Series where even made in HD in the First Place? If they weren't HD I may as well go with the Cheaper DVDs...

What do you Folks think?
