I have found that compressors have a hard time with slow fades to black of 
static scenes and white credit rolls on black. Both are common in TV and 
Film real world programs. An acceptable codec should not produce any 
distractions in this type of material.

Check out the work that Tektronix has done with their program quality 
analyzer. There should be white papers available as well as articles in the 
SMPTE Journal.
