Hi chewitt , thanks for the updated K20 image.
I just tried in on my S905 Box out of interest.
The image is in comparision to the K19 more unstable (expected as Kodi is alpha) and crashes a lot.
But with that Image it is possible to watch LiveTV in Mpeg2, which was not possible for your K19 images. Therefore the software decoder for Mpeg2 works good.
