Mpeg To Avi Pls Help Me !!!!!

[jaybro]

pls i need your help ?
i got the virtual dub as recommended on this site for joining avi files, and from the tutorial ive have mastered this (thanks alot) but what i also want to do is make my big mpegs to smaller sized files in the AVI type. ive tryed using virtual dub and from a 50meg mpeg i got an AVI at the size of 2.2gig LOL. some what i think this is wrong.
pls can u tell or help me use virtual dub to make avi's but with a lower file size.
or if virtual dub is not very good what do u recommend me to use to make my avis ?

you should use a codec to compress the avi.
Select video-> compression
