so 1st an i supposed to put an mpeg on the ipod? does it matter which folder i add it? where will i have to go on the pod to see it?
Unless you put the mpeg file on the player you won't be able to view it.

It doesn't matter where you put it. Simply copy the mpeg to some folder on your player. Then navigate to this folder by selecting "Files" from the Main Menu, select the file and it should play.
However it won't play properly (or not at all) unless you converted it to the right size and format. The wiki page mentioned earlier has lots of information concerning the conversion of videos for your ipod.
