Epson Home 6100/6500 work with burn vidoes or data files (pictures)?

So im trying to see if this will work but i dont want to mess up that expensive peace of hardware and plus its not mine and the owner wants to see if it works.

I currently have some Sony DVD+R from long ago and and some videos and data files to see if they will work. Does burning video files into ISO and such image format help make dvd players (Epson projectors) more compatible?
