My understanding was that you could just record straight to the tape - that TBCs were only needed for input, and that single-frame recorders were from the pre-Flyer days when mass storage of high quantities of video was not possible. Assuming I'm not wrong, try:
Make sure the Toaster's program out goes to the recorder's program in. Drop the anim into a new Toaster project file along with any other relevant croutons. Hit record on tape, hit play on Toaster, and that should do it.
Is it giving you an error, or just not working?
