When learning fingerstyle, there are all manner of scattered youtube videos, all manner of books and DVDs to choose from.
My general recommendation is to look for a comprehensive course of whatever format that provides not just the mechanics, but an understanding of what you are doing and why, as well as h0ow to directly apply it to playing music on the guitar.
My recommendation of Adam Rafferty's course is a good example of such a course. Obviously it isn't the only game in town, but is simply a good example of what I am talking about. These days, there is little need for the scatter approach as opposed to building a complete, solid foundation that doesn't waste time having to backtrack because later on, you realize that you hit a wall due to something you missed early on.
Mark Hanson was recommended here and, across his books and DVDs you can get excellent coverage. Toby Walker is another, as is Steve Krenz.

Here is one more: Six String Fingerpicking:

He goes from absolute beginner to a very high level of playing via his courses and he teaches a bunch of tunes you can choose from as well. All is very reasonably priced and the teaching is very clear and step by step.
There are many others, but if you look at all of these, you will see that they all build a solid foundation that includes, but is not limited to, just the mechanics of fingerstyle. Whatever materials you decide to work with, my recommendation is to look for building a comprehensive foundation rather than a scattered approach with a book here, a DVD there, and maybe a youtube video or two.
Watch the various samples of these teachers provided on youtube or on their respective sites and choose whichever teaching style fits your particular learning style and go to that site for the course.
