Two questions:

1. If I have burned a DVD, and it did not fill the DVD:
Can I add another small video to it?

2. Is there a way to add other files? For example, I burn DVDs with 'movies' that I create from Premier, that I've added some video, and some pics/stills, and audio. And I want to 'archive' the jpgs to the same DVD. If this is possible, what guidelines do I have to follow? I tried this once, and the DVD did not play in my player.

Thanks
