Well I cant answer the question asked, but related to that, I am looking at my season 1 DVDS, and at the bottom they clearly state "Includes English (uncensored) and French (censored) version." I think this is the first printing and release (Salter Street Films, Koch Vision).
I am just looking at season one here at the moment. Episode 1 has a sticker on it "Canadian Home Video Rating" of PG, same for episode 2. Episode 3 (Eatiing Pattern) has no sticker, then Episode 4 (Gigashadow) has a sticker and rating of 14A, whatever that means. I have only watched this on USA Sci Fi channel, so could well be i have unedited version I have never watched also.
I realize you are talking of season 2, which is confusing. Originally there were 4 films, 2 hours each, and this is commonly refered to as season 1, but it was never a "season" or show. When it became a "show" the episodes were started as if "season 2" In reality it was an 8 hour, in 4 parts, sci fi movie event, which served as a premier of sorts that was successul enough to warrent continuing with a weeklly tv show, which started as "Season 2" when it was really the first actual season. But it makes sense in the overall continuity of the story and films.
