Video Textures

I’m working on a scene with a television that I want to loop a video clip. I know that Blender 2.49 can do this, and I’ve looked at several tutorials, but none of them have worked. They just don’t make sense to me.
In one of them, it supplied a python script that was specific to the video file that THEY were using. I don’t know python, so how am I supposed to use that?
In another, it seemed like it would work, but when I played, all I got was a still image.
I’, quite confused, and need help here.

Just realized that I put this in Game Engine Resources. Could a mod move this to support?

Blender can only do this with a video file if your computer supports GLSL. Does it? Otherwise you need to make a tiled image. A good tutorial is at
