After I purchased the show from Amazon, I posted a review there about how grainy and washed out the shows looked. I soon learned that what I had inadvertently ordered was that "international" release. I thought that was the problem, so I sort of amended my review, assuming that it was due to the poor unofficial copies. I haven't seen any shows on the regular release DVD's.
Since then though I've noticed that even on TV the shows look grainy and sometimes a little washed out. Probably just me though. But the others shows seem to look fine to me on TV.
