Debbie, when you say the VCR/0618 code doesn't work, do you mean the remote says INVALID when you try to assign it, or do you mean it says SUCCESS but doesn't control your TiVo.

If it's the former see all the previous replies, if it's the latter, have you accidentally programmed your TiVo to use a specific unit code? If you have, this would explain why the 0618 code doesn't work. I'm not a TiVo user and I don't recall which screen you have to scroll to to set the unit code, so a TiVo user will have to help you with that if you don't know how to do it.

If nobody gives you the answer here, take the question over to the avsforum and they'll answer it for you.
