Excellent point Dale. MPEG-2 encoders have improved substantially in
recent years.
This also points to another "problem."
The entire approach to DTV operations is wrong in most stations. Most
facilities were built to operate at digital baseband for their
convenience. A better approach would be for the networks to deliver
optimized emission coded content (as Fox does), and use stream
splicing for local insertions. Recompression is not a good idea, and
it is even worse if the content producer took the time to use a
compressionist to clean up the rough spots.
