Ok, that's not helping. Basically when you do a quick press your receiver decides not to broadcast a key up event for some odd reason.
When you do a long press it does. To fix it you could try making sure you only do long press in MP or wait for MP 1.14 that should not have this problem on the volume key anymore because of some other fix. You may still have that problem when using the channel up and down key though.
That hasn’t fixed the problem, it has modified it, in so far as now if you press the key in the same direction, i.e. first press up, then press up again, it will stop the indicator bar, but still a bit hit or miss as to whether it will stop, sometimes it will, but not always, also the OSD will stall then disappear and not come back for about four or five seconds, so you have to wait to continue.
Thank you very much for trying to fix it for me, I shouldn’t have any troubles with the new amp as that is how I have been running the server, but if you have any ideas that you want to try out, I will most probably still have it set the way it is now, so should be able to try them out for you.
You don’t get this kind of help from commercial outfits do you?
The XML mods if properly applied should have fixed the problem. Double check that you don't have a custom setting file too in which case that's the one you need to modify. See documentation as linked above.
You could also just remove the VolumeIncrement and VolumeDecrement button sections from those XML files. Remove the mute section while you are at it.
