When I gave video evidence recently to a police officer, she simply gave me a CD-R and I was able to copy the video onto it without any problems. I then made sure that the video could be played back and it worked.
If the file is on the right type of format (My police station said that they needed continuous footage and could not accept storage data because it may have a virus on it) then there should be no problem. It was up to the court to make sure they could play the footage before the actual appearance.
Yes, because it's impossible to have a virus on a CD! Unbelievable; such techno-illiteracy.
