RE: Video editing software
Ulead MediaStudio Pro 8.0
Does everything you'll ever want to do and a bit more.
Might be a bit hard "on the learning curve" but in my humble opinion the most advanced video editing available commercially, and I can say I tried almost all.
Above this, your next option is proffessional studio software, expect to pay the price af a good mid-size car.....
If you want to start with some basic editing, Windows Movie Maker is your best option.
