Comment (by cehoyos):

 I tested the following:
 $ ffmpeg -i Sherlock\ S01E01\ sample.mkv -target pal-dvd -b:v 6450k -pass
 1 out.mpg
 $ ffmpeg -i Sherlock\ S01E01\ sample.mkv -target pal-dvd -b:v 6450k -pass
 2 out.mpg

 I don't see any quality issues with out.mpg.
 Please provide an input sample that allows to reproduce quality issues for
 the output file.

 Concerning the bitrate: Please understand that you cannot reach 6k for
 every input sample, if you encode with -qscale 2 you should see the
 approximate maximum file size.
