We need a re-release, as the UK discs only have 2.0 audio for Seasons 1 and 2, and the subtitles for Season 1 are hardcoded, which is not ideal. There are also loads of unskippable adverts on Seasons 2, 3 & 4... The Swedish releases for Season 1 and 2 have 5.1 audio, but only Season 1 has English subtitles, unfortunately. For Season 2, there is no release I know of that has both lossless 5.1 audio AND English subtitles.
