Hey all - I'm the person who uploaded the ten episodes this week, just wanted to say hi and say I'm happy that the find has had such a positive reaction in different corners of the internet. It's one of the only VHS tapes I kept all these years, as more and more of my off-air collection surfaced officially. My Reddit post has a bit more context: https://www.reddit.com/r/lostmedia/comments/1c0k4pf/found_noah_knows_best_2000_nickelodeon_sitcom_10/
I am of the belief that, short of cast and crew having copies, UK collections are the most likely source of the remaining episodes in English, as I've been able to verify (through physical TV listings magazines) that Nickelodeon UK aired at least 100 broadcasts of the show in total between November 2000 and February 2001.
Hello to you too, interesting, here's hoping they turn up. I would ask on the UK TV sub-reddit TV Bunny but unfortunately they changed the rules recently so that you can't request shows that aired on Pay TV in the UK anymore(as that's what got the old UK TV sub-reddit UK TV and Radio Land taken down apparently) and unfortunately Nick was a paid channel over there.
Would you happen to have any tapes of the UK sitcoms The Wild House and Genie in the House? there's a number of episodes of both missing still.
Went digging through threads on Anime Superhero and found out that the show also aired in Australia.
A Nick UK page apparently listed only 10 episodes of the show so that would explain why only 10 were shown on that marathon, though the other three may have been shown later.
Here's a Wayback page for Nick's Australian website for 2001 showing this show on it's schedule. I've got a contact in Australia and i'll see if they have anything from this show.
Forgot to mention that a few weeks ago I also asked Willie G's friend if Rachel Roth and Ken Lipman had any episodes of the show, he said he would ask them and let me know, haven't heard back yet but i'll let you know if I do(since Ken apparently works at Amazon TV studios now I definitely don't expect to hear back from him for quite some time).
