Get a copy of 'Avia' or 'Digital Video Essentials' (DVE). These are
reference DVD's with all sorts of patterns and instructions on helping
you set your TV up properly.
Also, some DVD players have the ability to adjust the black level to
(I think) 0IRE or 7.5IRE. Try one or other if possible.
Many digital broadcasts are compressed, and one way to help save
bandwidth is to reduce the contrast.
