Well the v2 was because of the wrong subtitles being muxed in originally, but it was released on the forum only. The v3 is because we've opted to add the 5.1 English Dub audio from the Adult Swim broadcast because it's a lot better quality than the 62kbps HE-AAC FUNimation Simulcast audio. Of course to sync it required edits however because both the OP & ED were cut and the preview isn't aired on Adult Swim either.
