The "Fault" is providing 1080i using MPEG-2 at a maximum bitrate of 17.5 Mbps.
Or 720 x 480 (even 24P) at a peak bit rate of 11 Mbps as is used for
DVDs. I have seen multiple studies that demonstrate that the peak bit
rate requirements for a 24P SDTV stream can reach 25-30 Mbps. With
DVDs we have compressionists that re-encode this difficult source to
fit the bit budget. Even with this i still see DVDs with blocking
artifacts.
