How can I put most video on a standard data DVD, but it allows only 2 hrs of video on it. Help!!!!?

Question

I have many videos of my college (more than about 9 hrs. total). I was thinking of taking them to home so that I can play them on my conventional DVD player. Since almost all of them are in AVI or other formats, I don't think that my DVD player at home will read them if I directly put them on a DVD and make a data DVD. So I needed to make a video DVD, one which was easily playable on almost all of the DVD players.
When I began burning, my software showed that only two hours of video was going to fit on a standard DVD (4.7 GB). I am confused cause every video is about one hour long and is of about 350MB. So if I make a data DVD, I will be able to put at least 12 videos, which equals 12 hours of video. But in DVD which I need to make, I can only put 2 hrs!!!!
Why is it so? I have also seen DVDs holding three complete movies and still playable on a standard DVD player. How did they make them? I want to fit highest amount of video I can, please tell me what should I do cause if there is
