Hey!
I've been running a Flash tutorial channel on Youtube for a couple of years now, you can check it out here. Recently I've started uploading a mini series of beginner tutorials, the first three of which you can view below.
I hope you find the videos useful and if you like the channel, please subscribe.

You should do one on how to make background layers move in different ways while using a vcam. Like parallax backgrounds in game use but with an animation using vcam instead. Maybe toss in a bit about using 3d rotation like in the door video to make walls or rooms appear to have more depth.
