Ive been watching "The Shield" over these last months picking up the box sets one at a time. I live in Region 2, and all the sets from 1 to 4 are 1.78:1 Anamorphic, filling up the screen of my Widescreen TV nicely. Ive just picked up season 5 on region 1 (not out in R2 for a long time yet) to discover that it's Full Frame 1.33:1; which is a surprise. Are the R1 sets of 1-4 this ratio too? Or have the R2 sets been altered?
