I've been using windows movie maker for my guitar videos and it's been okay. But I'm sure there's better free alternatives out there than what I have. With wmm I can't put more than one video on at the same time, it's bothersome to try and sync up a video towards the later part of the video due to the fact that if I skip to that, it automatically is out of sync, meaning I have to constantly start from the beginning and wait till that part to make sure it's in sync.

Any recommendations? I plan on upgrading all of my stuff this christmas, new camera (i know what I want), new audio recording software (any recommendations for those I'll take as well). I figured I might as well start with this since I can get it for free.
