There have been more reports about the need to completely de-install the HDMI-CEC plugin to stop it from receiving commands from the telly and sending commands to the box. Simply disabling the plugin doesn't seem to stop it completely from working.
And as VU uses a completely different IR-language from all other devices, interference with any RC is very unlikely (contrary to the Xtrends, who use a sub-language which results in much interference with many devices).
tomorrow you can try it. It should be solved.
