I downloaded a mp4 video from the web on my computer with good quality.
I converted it with the specified command with FFMPEG.
All did okay.
But when i write it on a DVD, my lector transmited some artefacts on my
monitor at every view changement.
Is it possible to convert with quality some mp4 videos to mpg with FFMPEG
or did i maked a mistake with the command.
Thanks
