Anyone having blackout issues, I highly suggest using a VPN service. I recently bought a year subscription to
Private Internet Access, and it's been well worth the $40 a year. It takes about 5 minutes to set up on a computer, and then you can use it to change your IP address to one in a different part of the country or some various countries in Europe.
I don't have cable, so I used it in conjunction with my MLB.TV subscription to stream Pirates games that would have normally been blacked out since I live in Pittsburgh. I didn't have any issues with it, and didn't see any loss in steaming quality either.
