Problem 1:
The zoom-out is (probably) a problem in the swf build we are running atm with phoenix. Aaron mentioned somewhere on his twitter that he can't fix the problem cause it isn't created by him/the zoom-out isn't suppose to do it. Now that you mention it, I'm wondering if it is fixed in upcoming 4.0 - You say you did find an youtube video, know by any chance if the retro you saw there was running on phoenix or any other? (than the problem could be again, swf build)
Problem 2:
Not sure what this solution is, it could be because the door is pointed somewhere out of the modelmap, or simply because you added the heightmap the wrong way.
