Thanks to all that replied to my post.
What seems to be the single most frustrating comment from the technical advisors over at the Roku forum is that, when told that netflix streams fine on any other device, that the roku uses a different cdn, and that the DNS that you're using may help. Here is one such exchange pulled from the Roku Netflix thread:

This is immaterial, as the computer connects to different CDNs than the Roku does.
As far as I've been able to research amazon's contract cdn's, the closest one to me in western Montana, would be Seattle. My primary DNS is my ISPs, which is located, physically, in Missoula. Suffice to say that my Wii uses whatever dns my router has, but it NEVER rebuffers when watching netflix.
Anyway, wanted to throw these comments into the mix to hear your technical responces.
