I finally have a MythTv box up and running with everything mostly working.
I have one final problem which I can not solve.
When any video is played back on the box it displays "cropped". In other words, the video shows only about the top-left 2/3 of the video. It doesn't matter if its full screen or in a window. Both mplayer and xine exhibit the same behavior and it happens with both live video and recorded clips.
Adjusting the video capture resolution does not make a difference.
I'm almost certain there must be a video overlay setting or something but having spent most of the weekend searching I'm mystified.
Any tips?
