This will work, The extreme works as well and so does the mini recorder. However it will have some latency, and minor little skips/lag here and there. Depends what FPS you want catalyst to output. At 59.94 or 60 none of these work that well...
if you choose 30 FPS, then it will probably be acceptable. Depends on what your source is, simple stuff is fine, fast live action, not so much.
