@ Thegerman8tor, Overplay currently don't support Channel 10 through SmartDNS. However, they are pretty good about adding new services if it is possible. Go to their support service (not the live one, but the full ticketing version) and request channel 10 from Australia to be included. Give them the link from above that Red Devil gave you, and tell them being a sporting event, it would be great if it could be tested before the event begins. I would write the support ticket today just to be sure, even if you can get it working on NBC as well - afterall, issues can exist with live streaming from other countries, so it would be good to have a plan B in case one goes down.
@ Red Devil, thanks for those two links!
