help with rotation

I've been wracking my wits on this issue. I'm trying to do some clean X/Y/Z rotations on a video clip upstream from some other processing. I'm trying to achieve the same type of rotation you get from the Sprite renderer. I've tried a couple of processes and they all have issues:

1. Tried embedding a sprite renderer within a Render in Image patch. It only displays if you turn off depth testing, but then you get those classic "Director-style" trails, which I don't don't need here.

2. Tried using Affine transform for just a Z axis rotation test, but the video dimensions stretch as you rotate, and the aspect ratio is lost. Moreover, the rendered area seems to expand vertically but not horizontally. What am I missing with these types of transformations?

There are some examples on Quartcompositions.com, but they all seem to suffer from the aspect ratio loss issue. Any suggestions?
