^It’s too bad that it was shot on video. In all honesty though, I’m not sure it would have the same feel without that video look to it.
Classic Who, like most BBC series, was shot on a combination of film and video. The restoration team went back to the original film when it could be found.
They could release restored episodes on Blu Ray with less compression though if there was a market for it.
Kind of annoying a bunch of stories are out of print now and have become Ebay fodder.
