Wow. That's a shame. I can watch TOS episodes in crystal clear high definition, the colors are sharp and bold, the lines crisp and detailed, yet TNG which was some 21 years later, looks old and outdated in quality. I guess they didn't think too far ahead on that one.
It's because TOS exists on film. You can just pick any resolution from there. TNG exists on videotape at the low resolution used by 80's/90's televisions, and flaws are accented with higher resolution devices.
