I purchased a Roku Stick to replace my Roku 3 based a recent c-net article that said "there's also a cross-platform search function that combs through several major TV and movie services to find content" http://screencast.com/t/yev5MPxtgIXQ
Unfortunately, despite claims from more than one source of a universal search improvement over the Roku3, it still appears that you have to search each individual service one-by-one, if you want to know what that service might be offering at any given time.
I used the cartoon Archer as a test which is currently showing up on the big three services (Amazon, Hulu Plus, and Netflix) individually. If using the 'universal search' feature in the Roku Streaming Media Stick, it only shows up on Amazon, and a service called Vudu, and does not appear to be available at Hulu Plus or Netflix even though it is actually available in all three places.
Is there any cross-platform search anywhere on the internet or elsewhere that will actually search across at least the 'big 3' Amazon, Hulu Plus, and Netflix media services for programming?
