Thanks for the suggestion. I tried trimming down the Roku feed to one item, and testing different configurations on different channels. I got it to work on one channel, but when i tried the exact same json feed on a different channel, it did not work. Go figure.
Does anyone know if the version number on the "Preview and Publish" page has anything to do with it? How can I get this bumped up? I tried changing the ID's on the json feed and clicking the "Refresh Now" button on the Feed Status. From what I can tell, that button does not do anything.
Anyways, am out of ideas. Any help would be appreciated.
