The Millenium 4 is a remote made by Universal Electronics, and the advanced codes posted above are typical of Samsung DVDs. The HD850, HD841, and HD960 all use the above advanced codes (frequently referred to as Extended Function Codes.) Most UEI remotes respond to numerically entered programming commands. Probably your remote will work with the following.
To simply try an EFC, make sure you have the correct device button selected, then press setup, and then enter the 3 digit EFC you wish to try. Do this first with an EFC from the above listing for a key that already works. That way you'll know that the test procedure works correctly.
Once you've found an EFC that has the desired functionality, you can assign the EFC to a remote key by using the 994 command, as described in this link: http://www.hifi-remote.com/forums/dl...b39c291246887b
