An external deinterlacer will only work if the output from MythTV is still interlaced, which isn't the case if the video has already been re-sampled by either scaling or deinterlacing. If you still have these artifacts after turning on deinterlacing, my guess would be that the deinterlacing is disabled for some reason. This could happen if you used XvMC or MythTV decided your PC couldn't handle the deinterlacing, which happens when you play the video at a a speed other than normal speed... If you are talking about MythTV showing two portions of two otherwise unmolested frames one on top of the other, this is probably due to AVSync problems. Usually, enabling OpenGL VSync fixes this. But most drivers allow you to enable/disable OpenGL VSync with kernel options, xorg.conf options, an external utility or environment variables. This is because the hardware often runs slower if you have VSync enabled, glxgears might always show 60 or 75 fps if it is enabled. Because of the "glxgears benchmark" the driver may even default to disabling VSync! -- Daniel
