Bottom line is that Window Movie Maker is a horrible NLE, very cheap and buggy. You might want to consider moving up to a decent NLE for PCs like Edius or Premier Pro CS5. However, the suggestion to use the free MPEG Streamclip is a good one. You can set your in and out points and export into almost any codec you may want. I have heard that it can be problematic on a PC. I wouldn't know but on a MAC it is perfectly stable.
Movie Maker is free, so I didn't expect much. I was very surprised how easy it is to use and how well it works with SD footage. My HDV footage stutters bad, but I can still edit it in Movie Maker.
My local UW photo/video club is 99% photo people. I've gotten some members to experiment with video on their point & shoots. For 1st timers shooting non HD, Movie Maker is very good to learn on. People who have never edited video often find the whole timeline concept confusing. The storyboard option is great for beginners and they can switch back and forth between timeline view and storyboard view.
After they get up to speed they can buy a better editing program. Maybe something at the entry or middle level from Adobe, Sony Vegas, Pinnicle. But, they have to get past the initial editing hurdle 1st. Many give up on video as a hobby because they don't know how to edit. Movie Maker can be worth a try for those type of people. Best of all, the software is free.
