[QUOTE="CyberSimian, post: 1175525, member: 141969"] You are not the only one. :( I thought that this capability was implemented as I had described above, but now that I look closely I cannot find anywhere where "0" is defined as "last viewed channel". :confused: It is not present in the "Generic HID" or "Microsoft MCE" config file, nor is it present in "keymap.xml". So where is it? I don't know, but the evidence seems to suggest that this definition is [b]hard coded in some MP source code[/b], and hence not alterable at all. :eek: Be that as it may, the following screen grab shows two alternative ways of defining the "Back" key to perform the "return to last viewed channel" function when watching live TV: [ATTACH]175975[/ATTACH] The first method changes the "Back" key into character "0". The second method invokes the "Last Viewed Channel" action. Both will return to the last viewed channel, but the former also shows an OSD with the name of the programme about to be viewed, whereas the latter does not (it changes the channel without displaying the OSD). I tested this with "Microsoft MCE" on MP 1.12, but "Generic HID" on MP 1.13 should be the same. The final problem is: which button to use on the remote? As defined in the screen grab shown above, you need only [b]one[/b] button, but my Harmony 650 has [b]two[/b] buttons that might be applicable: (1) A button labelled "Exit". (2) A button with a sideways "U" character with an arrow pointing to the left. In the default Harmony MCE config, both buttons have the same definition (I think), so they behave identically. If you wanted them to behave differently, you would need to modify the Harmony config so that one of the buttons sent a code for one of the currently-unused buttons supported by "Generic HID" or "Microsoft MCE" (e.g. the "Print" button). You then modify the MP config to map that button to the action that you want. -- from CyberSimian in the UK [/QUOTE]
