Those magnetmix files should download really quickly. If they don't, it can point to a problem with the ISP. I can't find any info about ihug blocking or shaping p2p, though.

How many green connection bars do you have?

(I phoned to upgrade my plan. To pay more money. I spoke to 3 different customer disservice officers. All 3 times I was put on hold & then disconnected after 15 minutes.)
