If you want to run .avi movies without converting to mp4 or 3gp this should do.
I been using it for almost a week and the video is smooth even with 700 to 900mb movies.
It comes with a converter that you might not need but if you have a movie in avi over 1gb you might get some chopiness with the converter you can trim the movie down to like 900 or 800 by bringing down the fps or kbs and if you dont over do it you wont even notice the difference in video quality also you will maintain an AVI format.
It has a free trial. test it out.
