Unfortunately, I don't believe that is possible. Anynet+ only passes some commands, not all of them.
I have a Samsung UNC6400 TV and just bought a Samsung BD-E5300 blu-ray player. I am able to control the Blu-Ray player with the TV remote with AnyNet+. The issue is I am not able to access the DVD menu (start screen) with the TV remote forcing me to keep both remotes. I have updated the software on both devices with no luck. Please let me know how I can access the DVD menu?
