Formatting devices

I have sourced 2 portable DVD players which both take USB, SD Card and DVD.. May use these to show a short film on a loop in final exhibition.

I have 2 possibly 3 tablets that can now play the film footage on mpeg2 files so are ready to go.

Also I have a 2 smart phones, they both don't take a memory card so going to investifate a way of storing a film to play on it.

These investigations always seem to take a long time.
