Bike Forums - Good Videos to Help a Beginner?

Hey, I just got a mountain bike a few weeks ago and have been riding every change I get. Love it! :) I've been sticking to basic "bike paths" so far to get the hang of riding. I'd like to start trying slightly more difficult trails soon, but I want to make sure I'm doing things "right."

I was trying to find videos on youtube, but most of my search results showed stuff from expert village... now, as an experienced drummer I can say that the "expert village" drumming-related videos are absolute garbage. For this reason, I'm not sure whether the advice given by them for biking is good or not.

So, as experienced riders, what are some good videos available for novice mountain bikers? I'm looking for basic stuff--posture, tackling small obstacles, proper shifting, safety, technique, etc... even some basic bike maintenance would be nice. I've found a few very good articles and such that have helped a lot, but I find that actually seeing this stuff in the form of a video helps out a lot more, especially since I'm teaching myself and haven't found other people to ride with yet.

Thanks for any hep!
