In case you still have problems with the feed you get from Vimeo, please check out Tappla.com
We help you to generate a Roku JSON feed (from the Vimeo API): you can organize your videos in multiple Vimeo showcases and then do the categorization and video-type selection in the Tappla dashboard.
(If there is a feature that you need and is not yet there, just send me a message and we try to build it asap)
Additionally, you can build a native Apple TV app at Tappla - working more or less the same as Roku Direct Publisher.
(full-disclosure: I'm one of the co-founders of Tappla)
