I have a Pioneer PDP-4280 TV which supports control of other equipment using CEC. By using the "HDMI control" button I can bring up a small temporary sub-window that allows media player functions like Play, Ffwd, Rwd, etc. to be sent to the source under control. (The source in the case is a XMBC player which doesn't have an IR sensor.) Otherwise it seems only the four direction keys and OK are available directly. TVs that do have play/pause etc. buttons on the remote (to control other kit) can send those commands directly using CEC. However, the PDP-4280 TV remote does not have those buttons. I use a Harmony remote for my AV system which can be programmed for arbitrary IR codes per button. Is there an established way of sending media playing functions to the TV directly that would get passed on (eg. by using Pioneer DVD player IR codes or something) to avoid me having to use the inconvenient sub-window? Otherwise I see my only choice as buying an IR remote dongle for the XBMC source.
