Yes, I've noticed that on the last three episodes aired (Mon/Tue/Wed of this week). But the season/episode listing on zap2it.com is a couple of numbers off (episode number) vs. what's shown on the IMDB page for Emergency. I do not recall the original open on NBC, so that made me wonder why toward the end of season one they would have changed the open. Now I know. Was the "syndication" open ever used on its first run later on? What's weird about it is that the Fuller/Troup credit titles seem always to be a light shade of blue, while the other stars' credits (London/Mantooth/Tighe) in the "syndie" open are true white. Have seen the same "some blue, some white" titles in some opens of Adam-12 on MeTV.
As to your "16mm" statement, I don't think that is true. Bad splices--yes, and dirty sections on the film--yes...but it definitely was from 35mm film. Probably the original 35mm prints were used when Universal was preparing the show for syndication.
