I made an account just to help you. I was messing with the settings, and underneath MEncoder there is another title you can click on called tsMuxeR. Click on that, and then untick the checkbox that says "Force FPS parsed from FFmpeg in the meta file". I also for good measure clicked on "Common Transcode settings, in the same place you find MEncoder and tsMuxeR and unticked the checkbox that says "Remux DVD ISO video track (no re-encode) (AviSynth not supported). Seems to be working great! Cheers!
