First.. THANKS! Yep, all I had to do was misspell Hulu... Huluu works fine, as does Huloo. So stupid.
In any case, yes, I am able to watch AmazonPrime and now Hulu full screen from JRMC21, accessed directly from Theater View. To get both of them to work, I used the same procedure; "Add Webpage," then pasted the urls in. For Amazon, I had logged into Prime from my regular browser first then navigated to my watchlist. I copied THAT url and used that as the webpage url in MC. Hulu's url doesn't change as you navigate w/in that site, for some reason, so I just used Hulu.com. It still shows me as logged in, perhaps because I had already entered in the necessary login info on the "services" section of MC's options setup menus.
Does that help?
Thanks again for the tip on changing the name "Hulu" to something else. Maybe I'll go w/ Poo-lu!
