When I am streaming Live TV, the video appears to be cropped, upside-down, squished, etc

It is possible that Orb may be using the wrong MPEG2 codec on your system. When Orb can't use the preferred MPEG2 codec, it tries the other ones until it finds one that works, and then sets that one as preferred.

Please try and change your codecs in Orb tray icon (Orb tray icon > Configuration > Advanced > Codecs) and try again.
