Hi Phil,

    Do you have OpenGL Vsync enabled in Mythtv TV Settings ? You might
have to recompile if the option is not there. Also what video driver
are you using ? If you are using NVIDIA you might want to enable the
other vsync settings in the driver properties. This solved bad tearing
that I was experiencing when watching a HD DVB-S broadcast and have
not had any since.
