Windows Media Center add cover and description to avi

How can I add cover and description to avi file, to see it in WMC? I tried the following:
movie1.avi (the movie)
movie1.jpg or movie1.avi.jpg (cover)
but it doesn't worked.
I tried the description add to avi with abcAVI Tag Editor, and... it doesn't worked :frown:
I found this:
movie1.txt or movie1.avi.txt
title="Title of Video"
genre="Genre Info"
description="Description of movie" and nothing.
Help me! I'm totally disappointed:scratch:
