Chances are they probably all are.

I don't think they are - I haven't seen that copyright message at the end before. Plus whenever the presenters say something like "next week TOTP is on at" or "don't forget TOTP2" channel names are written as BBC One / Two in the post-1997 spellings. But todays repeat simply used BBC2.

The thing that tipped me off early on was the things they used to do that they don't do now, like the background colour being blue to indicate a robotic voice, a red background for shouting, etc.
