This is the upgrade I was waiting for. Extras are so light as to be practically nonexistent (so one star deducted), but the shows are the thing. And they're beautiful on a large screen. The old DVD sets were not enhanced for 16x9 sets, and the transfers weren't that great. The new Blu-ray package definitely sets matters straight. Video is now quite clean and sound is more involving with all episodes mixed for 5.1.
Price is more than reasonable for all these shows in one collection (not counting the later series of TV movies set in India). American buyers need to be aware that the discs *are* locked to region "B", so they will need a region-switchable Blu-ray player.
