Adobe Developer Connection - Here is a massive amount of information that Adobe has collected on their products. You can find tutorials, support, links to popular bloggers in the community, and upcoming event. They have developer sections for Adobe AIR, Flash, and Flex. From new developer to seasoned veterans, its still a heaven of cool code examples and knowledge.
TheFlashBlog.com - A blog that is updated on a semi-day to day basis by Lee Brimelow. He gives tips, sneak peaks, product suggestions, video interviews, and conference wrap-ups.
gotoAndLearn.com - A lovely resource that had helped me out of many jams when I was first starting out as a Flash developer. Every video tutorial is created by Lee Brimelow an includes files you to work with and follow along. Use this site to your advantage.
theFWA.com - I am sometimes surprised that a lot of people haven't heard of this site. TheFWA awards other sites for good use of interactivity and design. All the sites are Flash/Flex. Its just cool to see what other people are creating with Flash and Flex.
Google - Type into Google's Search "as3 video player". I bet you'll find some examples and tutorials right away. Don't underestimate the power of Google's Search.
flashandmath.com - Hate math? Love Flash? Well you better start loving math because it can do some crazy sh*t in Flash. Browse around for tutorials about certain equations that can help with animations, game physics, hit detections, or just some crazy experimenting you want to do.
Actionscript.org - Actionscript.org is community that helps each other out. Its got a bunch of tutorials, articles and a decent forum. Join up to start reading/writing posts. Following along with other people problems might help you avoid some of you're own, but if you find yourself stuck and no where to turn, post it here. Someone will help out eventually.
Flashkit.com - I have never been a fan of FlashKit (do to user experience) but its still huge dripping mass of Flash knowledge. I find that most of what is on there is beginner-intermediate but if you are just starting out its a damn good resource. As long as its something simple, you'll find it here.
kirupa.com - I like to think of Kirupa.com as a cleaner version of FlashKit. Again most of the tutorials here are for the beginner-intermediate but there are some advanced(not too advanced) things scattered around. Its a must better design and user experience than FlashKit.
levitated.net Levitated has a nice amount of open source examples of interaction and animation. You can download the FLA and start picking apart the code till you understand how it was done. Enjoy!
All these link I have used at some point in my career. They are all great resources but there is a chance you may not find what you are looking for. You just have to dig deeper to find what you want for or join a forum to get help. Don't hesitate to join a forum, people want to help. If you have a good resource thats not listed here, please post it in the comments.
