Certain movies not playing – only black screen

Hi there, I have a problem with certain movies that won’t play since I got a new TV. Kodi simply shows a black screen. It kind of works when I disable hardware video acceleration, but video is then extremely slow at maybe 5 frames per second. I’m running Openelec 6.0.3 with Kodi v15.2 on a Raspberry Pi model B (I have no problems with Kodi on Windows 8 though).
Here is the debugging log. I would appreciate it a lot if someone could have a look into it.
