Perhaps I wasn't clear enough. I'm talking about the TV programme where Dan uses a small hand-held display similar to a laptop screen to show interviewees parts of the Friese-Greene film. I haven't found anything on the web site to indicate what he is using and I thought knowledgeable folks on this forum would instantly recognise it. Perhaps no one watches the programme.
Thanks for yours. They seem to move the "display" around and also poke it, which I thought a DVD player wouldn't stand, also it seems to be folded back on itself. I thought it must be some sort of solid-state device.
