hey dude, finally a forum post i can help out on, it really depends on what you want the software for, is it proffesional editing? a hobby? game editing? i would recommend after many many years of college (most retaken due to me being slack) that adobe premiere pro is the way to go, a very simple user interface, great for beginners and pros, a bit costly mind you! there are free editing software applications, if you are just looking to do it as a hobby then i would recommend windows movie maker, very simple and you can get great results, someone actually won a 200000 pound prize at a film festival using it! but other than that there is sony vegas pro! this is cheap software and you get some great results, think this retails at around 30 pounds, as opposed to premiere pro which is upwards of 200-300 pounds, but this software is a dream to use, that is my strong recommendation if you are willing to spend
