i had that problem with irss and tmt, too.
i ended disabling the plugins key translation (infact i disabled in the irss plugin options the "when minimized ...") and no i'm using only the irss translator.
i mapped most of the keys (audio/subtitle/popup menu/main menu/....)
i have attached the irss translator xml for my configuration.
That would be really nicebtw, if anyone wants i can upload my modified beta 8, i changed a lot.
sorry, i meant the require "focus option".sorry, I don't know which option do you mean?!? I just found an option "require Focus" in Plugin options and "enable keyboard input" in Server configuration.
I was surprised to see "Audio change" maped to "a". In User manual "L" is for change audio (and it works with non-mce mode of TMT and keyboad).
It seems that mce mode doesn't support "L", because with keyboard it doesn't work, too.
...
yeah, the standard tmt and the tmt mce differ a lot with the keymappings.
took me some time to figure out the necessary keys for blu-ray playback.
hope my xml helps.
