Yeah, it's difficult with this program, especially since I don't know most of what I'm doing. I just keep making stabs in the dark. I don't always have a preview option in this program, so I adjust it in a separate window, then hit preview to see how it turned out. But the truth is I'm getting decent results, so I'll keep trying for a bit and see how it turns out.

PS Thanks Ron for the suggestion. I actually found a pretty good quality version (same yellow crappy source, but as good as it gets), and I'm using that one. I suspect you will get better results, so keep at it too :)
