Are you kidding? DVD Region Codes

BBC's 'Extras', TV show... I bought this show from an Australian store (I live in Australia). As you can see, I've set my DVD drive to region 2, because certain DVD collections from England are limited edition, special collections and HAVE NEVER BEEN MADE FOR ANY OTHER REGION. Those special DVDs were for region 2 (BBC The Tudors collection $100, NOT MADE FOR ANY OTHER REGION, OKAY?). For 'Extras' TV series:

Disc 1 'season 1' works fine.

Disc 3 'season 2' works fine.

Disc 5!!!! Disc 5 is the special last episode! I CANNOT WATCH IT UNLESS I CHANGE THE REGION OF MY DVD DRIVE. ARE YOU ACTUALLY KIDDING? Why are there region code restrictions!? SO IF I WANT TO WATCH THE OTHER EPISODES THEN THIS AGAIN, I CAN ONLY CHANGE MY REGION 2 MORE TIMES!!?? EVER!? I WILL NEVER BE ABLE TO WATCH EITHER THIS EPISODE OR THE OTHER EPISODES, EVER AGAIN!? EVER?

THIS IS ROBBERY! MY COMPUTER AND THIS DISC ARE TRYING TO ROB ME! AND IF MY FINAL REGION CHANGE IS TO REGION 4, I WILL NEVER BE ABLE TO WATCH A SPECIAL EDITION DVD AGAIN!? A WASTE OF $100+! That is robbery, plain and simple. Only instead of a burglar earning a buck, it would be like the owner of the store I bought it from coming to my house to steal back the DVD.

NO WONDER DVDS ARE DEAD! NO WONDER DVD STORES AND SHOPS ARE CLOSING DOWN EVERYWHERE! Pathetic region codes killed DVDs. Is there no solution while I still have these discs?

WHY THE **** IS SOUTH AMERICA THE SAME AS THE AUSTRALIAN REGION, WHAT TV/ FILM WOULD I WANT FROM SOUTH AMERICA!?
