Best tipp for converting avi to mpeg: a program called TMPGEnc ;) you can get a freeware version of it online ;) the other way around (mpeg -> avi) VirtualDub is the best software (also available as freeware)..

In my opinion: when the guy doesn't want you in the first place or already has a girlfriend there's no need of fighting. You can't change his choice by fighting ;)
