Is there an unblocker service or equivalent where you do not have to disable one service to watch another?

I used to be able to watch tvnz on demand and aussie on demand services without changing settings through dns4me but this isn't the case now.

I find even with just using one service checked (7plus for example) I can only watch the live stream but not the on demand content even with all other services that would potentially conflict with it un-ticked.

I can understand a lot of the down under content is hosted by brightcove but is there anyway to get around this.

I think it's stupid I cannot use TVNZ on demand even though I live in NZ just because i have an aussie on demand service enabled.  

Rugbypass I'm finding I have to logout and log back in if I want to start watching something.  BBC/UK tv is probably the only services that I don't have to switch anything to watch.

Anyway theres my rant over.  If you have any solutions, please post.
