Pingu (1986-1998) - Any thoughts?

Hmmmm, back some years ago, there was a swedish user on YouTube posted the unedited original versions of the Pingu cartoons from 1986-1994, in which they were recorded from some B network in Sweden and with Swedish titles, and then another user called TheOriginalPingu uploaded the 1986-1989 cartoons in their original format.... so i see....

Well, originally, the opening was crude cel-animation, and the soundtrack was synthezied, just like the 1987 Gumby Adventures episodes, and plus the ending usually would credit Trickfilmstudio and Otmar Gutmann at the end...

But actually, the earliest i could find of the studio and Otmar Gutmann being credited were in 1990, the Pingu episodes made from 1986 to 1989 don't seem to credit anybody, nor do they have a copyrighted year date at the end, so expect those episodes to fall into the Public Domain anytime soon.

And during the 3rd season, Otmar Gutmann passed away (unclear how he died anyway.) so the credit was changed to Pingu Filmstudio begining in 1994, that same year, the better known and remembered Pingu theme and the better remembered claymated intro became the standard.....

I don't really understand why the original versions are extremely obscure and hard to find, those HiT entertainment butchers were done fairly recently, so i don't get why it's so hard to find, meanwhile CBBC and the Swedish B network is still airing and showing Pingu in it's original form and with the copyrights at the end.....

And HiT's versions of the episodes eventually started a new batch of episodes from 2003-2006, those featured a brighter and glossier look to the real-time animation and the voices and soundtracks were syntheized again, no longer falsely orcestrated as in 1994-1999, but this time none of the original people nor Pingu Filmstudio ever reprised their roles and everything was done by Keith Chapman's studio HOT Animation owned by HiT as well, and new actors assumed the roles of the characters and the modern episodes featured Keith Hopwood doing the soundtrack, any thoughs?
