Strange problem of animating bitmaps!

Hi,
I have come across a very strange problem while rotating bitmap images. I have a movieclip of an animated boat which needs to be given some movement so as to depict the floating effect. So i have tried to rotate it & have placed this movieclip on the first frame of a scene named Main. As long as i do not extend the frames beyond 1(i.e., one and only one keyframe as it appears at the moment)it works fine.
But the moment i try to extend the frames say from 1 - 5 or shift this movieclip to 2nd frame instead of 1st frame or rather even maintaining it on the first frame only but add a scene namely preloader before this main scene, it gives an absolutely dithered effect thereby destroying the quality of the bitmap as well as the animation. Can anybody tell me why does this happen & how can we overcome this problem?
However this occurs even with vectorised graphics although doesn’t dither to a very great extent but definitely dithers to some extent.

I have provided a sample for the same.You can locate the same at the following url: http://www.geocities.com/shuklahetal/bitmap.fla

Can this rotation effect exactly as is done my bitmap.fla file be acheived through scripting which can solve the above mentioned purpose of adding a scene before the main scene?
Please let me know regarding the same.

Awaiting a reply.

Thanks & Regards

hmm, do you just want to rotate something using actionscript? if so theres the _rotation thing. i’m not too sure about what you mean by the other stuff you said though :frowning:
