I'm in Australia, and I'm not having any problems...?
The only flaw so far(And it's only for setting up) is the XMLTV plugin refuses to overwrite the guide, so if it imports the wrong info, you have to remove it manually (I'm thinking anyway, else there is a big problem)
Like the guy above, what TV card are you using?
I've got a Dvico DVBT FusionHDTV Plus card and the only channel I can view is 7 Digital. I presume this is because TEN, Nine and ABC all use AC3 audio and something's going on that's stopping that from working...
Can you see all the channels? What SVN revision are you using for the TV server, and MP?
