I've never heard of a "Magic" cable box, if this box is really some other box re-packaged, then it's possible that there's a code in the remote, give the search function a try.
We could probably create a code for it using JP1, but we'd need a way to "see" what the Magic IR signals look like, and that would require either a learning JP1 remote (like the RS 15-2104, etc) or a Philips Pronto.
