This is the remainder of the Davison era. I have a full set of Fifth Doctor videos, although "Resurrection of the Daleks" is four 25-minute episodes, before it was re-edited into two 45-minute shows for broadcast, as a further example of the BBC's jiggery-pokery with the Dr. Who scheduling before this new episode length was made permanent in 1985. Until 1986.

"The Five Doctors" is the 90-minute version as originally broadcast. There have been more BBC releases of this story than any other, including the 4-part version broadcast in 1984, enhanced version, extended edition with new effects etc. etc. etc!!!! Why can't they leave well alone?!
