No, I have not gotten any replies yet.
Here is information of every US version I am aware of and have any information on.
PBS Version (Very rare, but the only way to watch the live action Halloween compilation movie and the 60 minute version of Holiday Special [The second one may not exist, I only found info on it from Wikipedia, which admits that the info needs citations]. Uncut, containing the full opening and closing, along with "Producer Says" segment. Contains opening and closing PBS "Funding for this program..." segment. May or may not have PBS Kids indent at the end)
Kidvision VHS /Warner Home Video VHS/DVD Version (Common. Uncut, containing the full opening and closing, along with "Producer Says" segment. Contains closing PBS "Funding for this program..." segment. May or may not contain an ad for the original books. Ends with the Kidvision or Warner Home Video logo, depending on what you're watching)
Fox Kids Version (Very rare. Opening and Closing are shortened, and "Producer Says" segment is cut)
TLC/Discovery Kids Version (Common on sites like YouTube. Opening is uncut, but Closing is shortened and the "Producer Says" segment is cut. When the show aired on these networks, it was always preceded by a "Ready Set Learn"/"The Taz Show" short, which may or may not be intact in online copies.)
Discovery Education Version (Rare, unless you have lots of money to fork, but infrequently some episodes of this version appear on the internet. Uncut, containing the full opening and closing, along with "Producer Says" segment. Episodes (at least the free one used as a teaser) start with a head leader containing basic information on the episode, followed by a 10 second countdown.
If you can get anything important out of this, let me know.
New Video Group DVD/Netflix Version (Common. [Mostly] Uncut, containing the full opening and closing, along with "Producer Says" segment.The reason I say "mostly" is because the Nelvana logo at the end is plastered.)
Qubo Version (Rare on the internet, as far as I know. Opening and Closing are shortened, and "Producer Says" segment is cut. May or may not be the same transfer as the Fox Kids version, and may or may not have the plastered Nelvana logo. I'm not sure myself)
This only covers versions that aired on the US. I don't know the technical differences between the transfers that appeared on other countries, but I do know that some of them localize the title card and theme music to their language [The italian version is especially notable, as it pretty much replaces the whole opening with a much longer one], and some of them plaster the Nelvana logo with the same logo used in the New Video Group version. I'm probably the only person interested in these technical details, but if I am not the only one, here it is! Enjoy!
