I must admit I am curious why the desire to go through the trouble of not only transferring the raw frames but then compile and compress them to play back in ANIM form, given it's an animation created on a PC that would ideally be played back as a full color AVI or Quicktime on that PC with direct access to the frames.
Regardless of all of this, something for the OP to keep in mind for future experiments in animation is that it is always a better idea to render to an image sequence, whether that's ILBM or TGA or whatever, regardless of platform or application, rather than directly to an ANIM file (or any compressed movie file), if for no other reason than in case you crash at frame 250 of a 500 frame render.
Compiling the frames to an ANIM as a post process offers more advantages than disadvantages and is a good habit to get into if you plan to ever do this sort of thing professionally.
