Blu Ray blank disc and burning movies?

I am looking into buying an external Blu Ray burner, as they are only about $200 now! Yes, they are very slow, but I like the idea of 25 gigabyte singles, and 50 gigabyte dual layers. My question is, on a single Blu Ray blank, would I be able to burn “regular-sized” .avi movies (700 mb or 1.4 gigabytes), and effectively put 10 plus movies on one disc? I wnat to play it on a Blu Ray player, not on the computer. Any information would be helpful!
