I finally figured it out a few hours ago. Now seeing US content.
Your last post is consistent with how I got it to work.
This whole exercise, while quite simple, has been totally frustrating and completely avoidable...its identical to making a recipe that everyone gives you, but each one leave out an ingredient. Or a dozen manuals, each one leave out a different page. No wonder it was frustrating.
For the benefit of others new to roku, I will one day write up the whole, very simple, procedure, top to bottom, without leaving anything out, but am way too exhausted to do it now.
The missing piece was....... that in addition to setting up the router with the proper DNS setting (and sorting out multiple routers if one need Canadian only content, with correct DCHP options, IP ranges and LAN vs WAN connections) , and testing to get ALL RIGHT confirmation from unblock, and only then setting up the one-time roku account with an appropriate US address/postal and paypal/credit info, and following all the detailed setup instructions, and connecting the pc (and later the roku) to that router.....one must ALSO use those same DNS settings on the pc used to for the on-time creation of the account. Yes that point is in the troubleshooting section, to figure out AFTER you get in trouble, but its not in the setup instructions. At least it was clear to me, as I was not using unlock for my computer, only for roku, so I read thru the roku setup only.
UPDATE - I even checked my emails from unblock.. they themselves guided me wrong (or at the very least let me fall into the trap I did : " "As you cannot change the DNS on the Roku directly this must be done on the router, so any other devices on the same network, including computers, will also be setup to use our service. This means that there is no need to setup your computer individually as the router is already setup. " What they say is true to get Roki working , but not true toi get it working for US content..which is the whole point of unblock-us!!!
