As I said, season 1 episodes do not have subtitled commentaries, at least in the DVDs I own (region 2, with German and Spanish voiceovers). Season 2 and season 3 DVDs *have* subtitled commentaries, but season 1 does not. Or, if it does, I have been utterly unable to find them (and, believe me, I have tried).
So, although I *already* have all the sets, I still would appreciate transcripts of the season 1 commentaries (easier for me to understand written English than spoken English, and I still don't get certain parts of the commentaries in season 1). I would then read the transcripts, and would be able to watch the episode with commentaries with a much better knowledge of what they are saying
But I guess that nobody has made those transcripts, so it will remain an unattainable dream, or something like that...
