I have compared the two sets. Every episode is 'longer' in the Network version, the difference in length varying between 24 and 47 seconds (and 54 seconds for the Christmas special). You can see how this happens just by looking at the first episode; the extra 45 seconds is approximately equally contributed to (and fully accounted for) by the retention of the ad 'bumpers' (which are cut from the Cinema Club release) and a prolonged still of the TV company logo at the end. It's therefore not at all likely that a substantial scene is missing from one set and not the other.
If the scenes you describe exist, I'm pretty sure that Network would not have cut them out deliberately.
