Choppy half the story lines are audio only - no video
The DVDs were a combination of video and audio episodes split evenly and set up alternately so a series consisted of part 1 video, part 2, audio only, part 3 video and 4 was audio only. This left the story very choppy and hard to relate to the characters. This step up was a surprise based on the product description. I would not have purchased this if I understood that the stories were not completely in video format, audio does not work well for us.
A small glimpse at some of the lost episodes. Combined with telesnaps and animations that exist on youtube, you can piece together entire lost serials. For example, with this disc and finding Loose Cannons work, I have seen the entirety of The Daleks Master plan.
A must for a Who nut!
