For those of you who weren't at NYAF, there's good news-- maybe. The 30-minute one-man-band show is available on the Playstation Store in Japan, and if you have a Japanese account for downloading games and the like, and you have ¥500 (about $5.70 USD) in there, you can rent an SD copy for three days, complete with some special extras...theoretically, anyway.
See, I know this works for games, which are region-free for the PS3, but I'm not at all sure whether video works the same way, and unfortunately, I don't have access to the PS3 in the office and won't have it all holidway weekend. And even if it DOES work, it'll be a hassle-- here's a video I found with instructions on adding yen to your Japanese PSN account:
It may be a pain, but I know there are Cencoroll fans out there who would love the opportunity to support creator Atsuya Uki's endeavor. But if there's any kind of region encoding or IP address check on the video, it may not work. If one of you checks it out for me and lets us know if it works, you'll be my new favorite!
Easier to just import the DVD imo...
omo is correct only the games store has no region lock the video and television shows in the PSN store (same goes for Blu-ray discs) are region locked and would require a Japanese proxy server, which is another can of worms.
Or if you want to take a chance to get yourself banned (I'm not sure about bricking Sony doesn't seem as concerned as Microsoft is about this) you can probably find some homebrew firmware that violates the EULA and would allow you to do this but all I will say is I don't condone this and if someone wants to do something stupid like that I would warn them to be very careful. (especially since it's a pretty moronic move to try to access PSN with a modified PS3 through some backdoor or other exploit to begin with)
