Ray Darr, there is another option to those already mentioned above, and that is Movie Edit Pro 2004. Retails at approx £50, and has 16 channels that you can put anything into (audio, video, stills etc.). The interface is not as easy as Pinnacle Studio, which I also use, but it does have some nifty tricks up its sleeves. It has blue/green/white and black screen capability which allows you loads of picture in picture options, and 16 channels means you could have 16 videos in your production without having to do too much cutting. It also has quite a good DVD authoring section with intro movies, sound and animated menus.
As I say it is not as easy to use as Pinnacle, but gives several more options and tools, and is nowhere near as expensive as Premiere, which seems to do it all.
