same problem here too. And it occurs on nearly each program change. The
backend has a problem to switch fast enough to the next file, therefore
the frontend gets stuck. Sometimes it lasts too long and the frontend
jumps to main menu with a video-buffering error.
On H264 content often the first frames are broken (perhaps new file
don't start at a keyframe?).
