Some good points above by several posters.
So my friend comes over and watches an episode of TNG with me and I remark on the quality. He says it just reminds him of when the show was originally on cable and says I've become spoiled to DVD and HD. He's right.
However, his idea that it looks like how the show appeared on our local cable stations back in 1987/88 gives me an idea to simply pretend that's what I'm watching once more. Not a bad way to convince me, I might add.
