I think SaveMovie() like the other functions in animation package has a nasty trick of changing directories under the hood and then changing them back. For my work with animation I hacked that part out of the packages source code [ in ani.start(), ani.stop() ]
Jacob, As long as the function takes a raster Object (grin) I think the code from either of those projects would work fine in an R package. it's been a while for me since playing around with video codecs, or I'd volunteer, but I can sign up for bug testing.
