So if I just burned say like five files in the .mov, .avi, and .mpg formats and then put that DVD in the non-computer player, it would not even recognize it?
It depends a lot on the brand of the player...and how new it is.
Most newer machines are supposed to recognize most burned discs...and many file-types--
now they've thrown in dual-layer DVD's because there is more capacity-- and that's what the studios use.
The only way to find out is to try it, unfortunately
