I picked up Doctor Snuggles from the UK.  It's a 4 disc box set with interviews and commentaries.  If you look around you might find a torrent of it.  It's most likely mine as I searched everywhere for these episodes before finally breaking down and buying a hard copy of all of them.  The format I have is PAL which is why I converted them all to digital.  Maybe the copy you have originated from me!  

Jeremy the bear!  A classic!  I remember that one, it came on right after/before "Fables Of The Green Forest" which is another series I'd purchase in a heartbeat if I could only find it.
Last Unicorn you can pick up for a tenner at your local Future Shop on Blu-ray.  I still think it's the best thing Jeff Bridges ever did.  It is dark for a cartoon.  I watched in the theatre back when I was 12 or 13 and I remember it making an impact.  Not because it was scary, just because it was the first cartoon I had ever seen to illicit fear in me.  Until Last Unicorn, I didn't know cartoons could be anything but funny or fun to watch.  I'll wait on this one to show to my kids.  They don't need to see a harpy eating Mommy Fortuna (Angela Lansbury) alive while she screams to death.  I watched it with my wife the other week.  After it was done she just looked at me and said "I don't know you at all".  We've been married 5 years.
