I've reinstalled JD, and all of a sudden the direct download is working too. Slowly but surely. On another note, I have BDRips of all the 6 movies (4 size 8,5 GB, 2 23,8 GB) But I have no Idea what would be handiest to get them to you. At least they're already up in newsgroups.
Edit: Only Eps. 2 + 3 (the 23 GB ones) look decent. The 9GB do not, which is understandable yet weird since they looked really crisp op my friends HD tv. But I'm not that technically knowledgable I'm afraid.
