do they speak english in what?

Today I have been experimenting with ffmpegX which is a video/audio movie encoder supporting many formats for OS X. I have noticed some of the recommended options which the author suggests on the site, produce undesired effects on the video. Not a good thing. I wasted hours of good encoding time, making a bad copy of a video. Thank you. Now, I'm experimenting with scenes from movies instead of full 23 minute TV episodes ripped from DVD. This should lower my wasted time, you think?
