Failing television,Region 4 [Australia]best way to go, if 你 are a big 粉丝 like me, and dont mind footing the change.You can get Season 8,which is a three disc set and includes the remaining four episodes of Season 6 and the first nine episodes of Season 7 (Back to the Woods - The 果汁 Is Loose).It also includes some neat special features like commentaries on every episode, deleted scenes, and featurettes including footage from Comic Con 2008. Thats the best I can tell 你 as I am from the States (U.S.A.)Also I believe the distributor is 狐狸 首页 entertainment. I will try to find out 更多 if I can, (like where on net 你 can buy it if at all interested) Please feel free to drop me a mail if 你 care too. It would be my pleasure to help if I can.
