A good learning remote.... I have used 3 different remotes with my media center since I have owned it... and never have used the original remote.
My MX-800 even come with the codes for media center in it's IR code editor.

There is a trick though media center needs some settings changed if you get the problem of a button working for one push but not a second push... then there is a setting you must do to make your remote work... If you need this let me know and I will send you how to make these settings...
