This may well be a question for atrpms-users or mythtv-dev, but I
thought I'd try here first. Forgive me if this isn't the appropriate

From what I gather, XvMC-OpenGL handles frame rate conversion better

will only display 1280x720 at 60Hz. As such, you get a very slight
frame jitter due to the frame duplication to make the 50Hz
deinterlaced source play back at 60Hz. Will XvMC-OpenGL offer an
