AVI Texture Problem

HI I have an AVI isue with my textures.
I have been working on a project over the past few months. This project uses several AVIs as textures and all worked well- howether.
I have had to re-install W7 on my system and now when I load my project Blender 2.49 can not recognise the AVIs " Can not get image".
I do not remember installing any codec onto my system in the past. Most of the AVI are uncompressed produced by Premier. I have made a small test uncompressed AVI and blender cant load it.
Some of the AVIs I used were using compresion but I cant remember what type, however Blender could use them.

Im at a loss
Any sugestions ?
Thanks

A good reason not to use AVIs, EVER. Find a program or old computer that will read them and render them out as a PNG sequence.
