>>112829640I know there's a set of torrents for the full set, S1-2 720p, S3 1080p, all with 5.1 audio. Never actually downloaded them all though, so can't guarantee they'll still work.

Interested to know where/how you got the S1-2 1080's from though - if they don't have surround audio then someone could combine them with these, if they seed properly.
