There are plenty of remotes to do just that. I'm a huge fan of my Harmony 880 remote, not only controls everything I own but also turns all of the right equipment on for different things; ie, watching tv, dvd's, or listening to cd's. I don't think I'll be getting rid of it anytime soon, other upgrades included. The setup software for the remote web interfaces and gets all of the info that your original equipment remotes has(if not more) and then programs the remote with them. Get a new tv just go in change to that one in the software, hook the remote to the computer, it reprograms and away you go.
Look around I know there are other brands out there, just find what you like.
