Changes (by cehoyos):

 * keywords:  mpeg2video, dvd => mpeg2video dvd
 * version:  unspecified => git-master


 You could compare the output file size with the following:
 $ ffmpeg -i Sherlock\ S01E01.mp4 -s 720x576 -qscale 2 -acodec ac3 -ab 448k

 If you still see the blocks and other quality issues, try to cut the
 relevant part from the original sample with:
 $ ffmpeg -ss xxx -i Sherlock\ S01E01.mp4 -vcodec copy -t yyy out.h264
 and provide the sample (if it does not show the same visual problems)
