Short Camera Pal

*computer techies* how do I make video 720x576 resolution, PAL format and as an .avi file?
I filmed a short 30 second clip on my digital camera, and I want to send it in to a television competition. The requirements ask that:
If you are sending a video on DVD ROM or CD ROM, it must be in avi format and saved in full resolution (720x576 @ 25 frames per second) for broadcasting purposes. Please ensure your computer editing programme's project settings are PAL (625/50) upper field first and not NTSC (525/60).
How do I do this? I know that at the moment it is 30fps and have managed to resize it so that it is now 720x576 res and .avi BUT how do I burn it so that it is PAL format and remains .avi? What program can I use to burn it this way that I wont have to buy (free download) and how do I use it?
your help would be VERY much appreciated. (and I'm too much of a noob to figure this out)
