OK, thanks for that. The 4660 is the one Ultra I don't have. I'm watching my Ultra 4670 right now, and Prime is working for me. I don't use Hulu, so can't test that.
Now, this Ultra is still on Roku OS 10.0, while my Ultra 4800 and Premiere 3920 are both on 10.5. But all three seem to be working fine. I'll let Prime play for a while, since I'm just sitting here waiting to see if any trick-or-treaters show up. 🙂
