With the Canadian release of the Zune today, I installed the Zune softwre on one of my PC’s that didn’t have it. The software looks the same as the other versions I have except that there is no option for the Zune Marketplace. While this is not a big deal as you can’t buy music outside the US and without a US credit card, you can’t download free podcasts either.
I signed in with both my US based Zune account and my Canadian Xbox live account and still could not see the Marketplace option.
I Googled it and it looks like there is a fix that is pretty easy. Just follow the instructions on this site.
It is a very simple fix and I can confirm that it works. I can subscribe to podcasts via the Marketplace even signed in with my Canadian XBox Live account.
Otherwise the software seems to work fine.
