Watching Robin Hood on CH4 today I found that when first switching to that channel the aspect ratio was OK.But after about 20 sec the screen would push the picture to the top and bottom causing the images to be stretched. I have a panasonic Viera TV connected to the HDR and watching the same channel through the TV source the aspect ratio is OK but through the HDR it seems to loose the correct aspect ratio after a few secs. This is only Live TV and not the same prob I have seen on the forum with streaming etc. Both the TV and HDR aspect ratio settings are set to auto. The only way I can improve the situation is to set the Panny TV aspect ratio to 16:9. But this can mess up other channels.
