Let me preface this by saying that I have pretty close to state of the art system and I completely understand that dvd's will not come anywhere near the quality Blu-ray will offer.
That said TNG looks terrible even with my Blu-ray player upconverting them. Other older (same era as TNG) dvd's I have look significantly better.
Is it just me or does TNG not look very good in the dvd format?
I just have regular DVDs and no upconversion/HDTV. For me, the first season is a little "blurry" (some episodes more than others), but the later seasons get progressively better. I suspect it's just that the original mastercopy has those problems, so I doubt much can actually be done. For me, apart from one or two first season eps where it's very noticeable, the video quality, doesn't detract from my enjoyment of the series. But I suspect this may be a YMMV sort of topic.
