Right, movie files are broken down into video and audio components. Each component comes in a format, and if you use the wrong format or the wrong options, you'll get a very large file.
Anyway, out of mpeg, mpg, quicktime, and avi, we can eliminate quicktime because it is not a format. It is a media player. That leaves us with AVI. We can eliminate that as well because it is not a video format, it is a container. Your movie might be an AVI, but it does us no good if the actual video format is a bad choice.
Which leaves us MPEG and MPG, which are the same thing. Ok, so I'll assume your question to be "how do I avoid super huge movie files". The answer is pick good codecs for audio and video. I'll refer to the list on Wikipedia (http://en.wikipedia.org/wiki/List_of_codecs ) and point you in a few directions.
Mpeg-4 is a solid choice. If you choose Mpeg-4, you should use XviD.
The other very solid choice is H.264. Most encoders for H.264 cost money but you have the solid alternative X264 (http://en.wikipedia.org/wiki/X264 ).
You also need an audio format. Good choices are MP3 (a bit dated), and AAC (newer and better).
Oh and you need a container for the A/V streams. Take a look at the list at Wikipedia again (http://en.wikipedia.org/wiki/Container_format_%28digital%29 ). AVI is a widely used container. It's dated and there's better alternatives. They are MP4 and Matroska.

It really depends on what you are recording. If it is high motion video, I would recommend DivX or XviD encoded AVI's. If it is extremely low motion, such as recording from a computer screen within Windows, you will usually find that QuickTime offers the smallest file sizes.
High Motion Compressed DivX AVI's work out on average 700MB per 100minutes *approximately* at a 700ish bitrate.

AVI is the smallest out of those I believe. If you want an even smaller file, try using WMV...the quality suffers, but the size is small.
