[Q] Video image inversion topic

I am running MX Player on a Neocore C1. When I open MX Player everything is as you would expect. However, if I have the tablet oriented, landscape fashion, with the physical interfaces, i.e., sockets and buttons on the left-hand side, when the video is run, the image inverts 180 degrees. This does not happen if the sockets etc., are to the right-hand side.

I am experiencing the same effect with BBC iPlayer.

Any thoughts anyone on why this is happening?
