Howdy, this will sound stupid but . . . .

What is the math behind figuring out how big an MPEG2 will become from an AVI? ie, bit rate, one pass, etc?

I have some AVI that I want to convert to MPEG2s and keep them about 1.1 gbs each (44 minute AVIs -- about 350 Megs). What sort of setting should I use?

Hope some one can help the green newbie.
