Season 1 and 2 are from the new series
I have all of Peter Davison and a few adventures of Tom Baker on DVD...
On Video Tape I have Shada, ARc of Infinity and then taped eppies from when it was on the public telly here. I have several adventures of the 1, 2, 3, 4, 5, 6, and 7. I also have K-9 and Company on tape.
Many adventures of 1 and 2 are either missing or incomplete due to the BBC either discarding the episodes or reusing the tapes. It was a typical practice up until 1980s to do that. It was a practice also done in the US.
I do not have the Fox movie any longer after my vcr decided to make a snack out of it and it broke the tape!
I do have many of the novelizations of the scripts from all 7.
Most of what I had on tape is gone, lost during the move.
DVD:
First Doctor: An Unearthly Child, The Daleks, Edge of Distruction, and a condensed version of Marco Polo, in a collection called "The Beginnings."
Second Doctor: Tomb of the Cybermen.
Third Doctor: Spearhead from Space, Inferno, The Three Doctors.
Fourth Doctor: Pyramids of Mars, The Hand of Fear, The Robots of Death, the entire Key to Time season, City of Death.
Fifth Doctor: Earthshock, The Five Doctors.
Sixth Doctor: The Mark of the Rani, The Two Doctors
Seventh Doctor: The Curse of Fenric
I've all of the Target novelizations, somewhere in the basement.
I'm having to stick to the American DVD transfers, not having a region 2 player (and I'm
not going to ask der B to get us one, no matter how much he begs).
The Eighth Doctor movie, aka The Enemy Within, is apparently tied up in legal glitches, which is why it's not out on DVD.
