I've noticed this issue with two separate files now. What happens is that the video will stream well, no stuttering, sound is fine, but the image shifts left and right constantly. There is also a little green 'bar' in the lower right of the screen, probably about 10% of the length of the screen.

Any suggestions? The video file tonight was an mkv I made that was transcoding.

I can provide any more useful information so long as I know what might be useful Thanks.
