Are you sure? Can you check the Slingplayer Desktop to or Web Slingplayer, to see if the Channel Up and Down are actually working? This is because the Setup Assistant uploads th IR codes to the Slingbox Each IR code comes with an associated keymap. For most remotes, "Channel Up" is typically keymap "004" and "Channel Down" is "005". This allows the Slingplayer client to be agnostic about the IR codes for the set-top box. Instead it just tells the Slingbox the matching keymap number of the button which you're pressing.
Just gave it a try.
Commands do work right from Slingplayer desktop.
I can change channels up and down with the remote on the desktop. Also, my keyboard up and down arrows change channels up and down correctly.
I am 200 miles from home right now, so this is all done through the slingbox.
Ps Thanks for the rapid reply.
