If you live in the U.S. or Canada, I'd be willing to snail mail a DVD of episodes 1-100 (from the torrent). Just send me a PM with your address.
A very friendly offer thank you, unfortunately I live in the third world part of Germany.

@Rolf I have left a message for jEsuSdA.
Can you send me a PM with your location? I only know the first and second world part of Germany

Unfortunately, I only have one single original DVD of the first 100 episodes left, which I want to keep for myself

But I could make a copy. Or have you already found a working torrent?
Or can somebody recommend a free (or cheap) storage service where I can put a 4-5GB file (DVD image) for download? My different web spaces don't have that much free space and I also don't have a server running.
My upload at university is super fast - I could upload the file within few minutes. So a storage service or somebody running a server where I can upload the file to would be great!
