I also have trouble with the date & time. No big deal, but must be a bug. I have not had a problem with the remote losing codes. I always rewrite my remote from the PC. I happen to like this remote and the PC interface. I do not have many of the problem some are talking about. But I also happen to like many of the Microsoft products. Happen to think that is the reason for the bad press in this forum. All my units pickup the IR 15 - 20 feet out without any problem.
