and that's just the ones off the top of my head.
You may notice that Stargate is in both the Region 4 list (Region 4 is Australia) and the Region 1 list. That's because in Australia the first Stargate DVD has the pilot and the last three episodes of season 1. DVD 2 continues on from season 2. If I want the rest of season 1, I need to get the Region 1 version.
