Hey Jerry, just discovered this thread; I like very much your efforts, and the fact that, even if I don't love the Pooh, it will have a proper release.
Personally, as the files you are working on are all AVC encoded, I will leave them "as is", using BD-25 (4 should fit the entire series), and "simple" AVCHD on DVD-5, or BD-5 for the ones who has not a BD burner. Of course, you could always release DVD, too. It's up to you, but to be widespread, I'll do them all, plus "raw" MKV with FLAC for english as well.
Good job!
