I was watching Season 5 episodes on TVLand, and they look very bad. They look too high in contrast - too much white in the light spots, and too much dark in the dark spots. Plus, the audio quality is also bad.

I noticed that too. Everything seemed too dark.

hmm I haven't noticed that

It may have just been on Saturday, but it seemed like all the episodes for about a 3 or 4 hour block that afternoon/evening were too dark.
