RWBY Volume 1-7 Bluray Remux DTS-HD -Seasons 1-7 according to TVDB. Season 1 had a handful of two part episodes that were combined on the bluray. -Remux is from North American Bluray. -Subtitles and audio are english only. -First 4 seasons were only in dolby digital 5.1 despite their boxes being marked for DTS-HD. This also applies to the newer 1-7 collection box.
翻译说1到4才有5.1，但我亲自下载下来看信息确认了一下，还好啊，没什么不一样的。
