Someone contacted us (Peter Pan team) regarding missing DVB subtitle on this channel. After some time people in the same thread also reportet the same issue for other image makers eg. OpenPli, OpenATV, and also for other tuner producers like Mutant.
Could this be somewhat the same issue discussed i OpenPli forum in 2010. Then there was discusses three other channels with the same problem. It was mentioned in this thread some framebuffer acelleration not supported by the driver.

Have tested a bit and the subtitle box comes around after a while but it is transparent with no text in it.
