You can use either DVD or Memory stick. I use DVDs, put them in a DVD case, nice picture slip outside the cover, print picture on the DVD plus text, and on the inside a print with appropriate info. Of course, it all depends on the users TV, DVD player; some later model TVs have a memory stick input.
I use an A3 canon printer that can print on the DVD. The Canon printer has special software that you can use to make the DVD cover with text as well on the DVD. Further photo software, paper. Also, best to use 16x9 images to fill the whole screen.
If you need more info and images best to do this via email.
Good luck and stay away from Corona!
