One word: Reboot

e: @Zokier i downloaded the remote for my telly and the volume + and - works, the off button works but won't turn it on, the channel + and - works but will only change one channel down or up and then nothing, ifi wait some time it will change one channel in the same direction again, but in that way it will take several min. to get through 20 channels.
I can see the telly reacts on the press on the channel changing buttons.
Is it a bug or just the remote the way it's set up from phillips?
Have had qtirreco installed and that worked fine with the same remote, no delay or not reacting
