The versions of the four supershows of Friends that are on the season 7 DVDs, are those the entire 40 minutes extended shows? They last about 29-30 minutes, so that would mean 10 minutes of commercials, is that realistic? (I'm not from the US so I haven't seen the extended versions). Also, in an episode guide it says something was certainly cut out of "The one where they all turn thirty" as a guest star is missing and the episode is only about 24 minutes. Anyone know why?
