One was in the late 2000s the other 2020s.&lt;p&gt;One of the challenges for the project was finding working 1-inch analog video machines. The team scoured the world for machines, working or not, and managed to get several running. There is one particular part that fails, Sony only has a handful left and the machinery to make them is no longer available. When they are gone the media will be unplayable.&lt;p&gt;The data complexity was due in part to there being multiple version of various quality, a program can be split across multiple tapes, and tapes can have multiple programs. So they need to ensure that all tapes of the best versions were selected, and also know what parts of other programs were on the tapes – bonus material. Finally, it was common to re-use video tapes to save money so it was possible that rare fragments of other material could be found at the end of the expected programs.</text></comment>
