I said older ones where it is as good as it is going to look. Like for instance Doctor Who. If the show was shot on SD video tape it is not going to look any better on Bluray.
Now yes I do collect filmed TV like Star Trek, Dick Van Dyke, and other shows on Bluray but quite a few older shows were shot on SD video tape. Most of the BBC's older output was in this format and film copies were only made for over seas sales but even then it was film copies of stuff shot on video tape so it's not going to look any better on Bluray. That is what i was talking about.
