You can forget a petition. They will not release it in region 1 until they are convince there is abig enough market for it.
My simple advice: get an all region dvd player. They are available on the internet for around $300 now, icl. shipping. There are no special connections, same as a regular one. Consider that the dvds are going to cost at least around $100, 13 episodes, same as I CLAUDIUS I would think. It would make the investment worthwhile and you are ready for the next thing to come out-region 2 only.
Also, see if it is available in Canada, they are region 1 but have a different distribution arrangement & ofetn have a lot of BBC shows not available here, like the Prince John series a while back.
Anyway, my copy will be waiting for me when I arrive in England this winter- my friends know me very well indeed, didn't even have to drop a hint
