Adding data to a video DVD?

This is kind of a newbie question. I’ve downloaded a video (perfectly legal, just to get it out of the way). It came as a collection of files within a VIDEO_TS directory. If I burn it to a DVD, it will become a regular video DVD, playable in a stand-alone DVD player. I’ve done this before. But this time I want to add some data to it, like information about recording, artwork, that sort of thing. If I create another directory off the root of the DVD, will it still be playable in a stand-alone player? Or does it have to be named in a certain way to be compatible?

Thanx in advance,

you can do anything you want with the dvd as long as you keep the video files in the VIDEO_TS directory and burn it with a UDF filesystem. other data files can go anywhere you want.
