I'm working through the ECP commands and I'm unable to determine the contentIDs for Sling. The goal is simplified interface that is able to directly launch a number a given Sling TV channels. It's funny that the query/media-player returns minutia on bit rates but not higher level info on what's playing.
contentID is channel specific and I doubt if it will be exposed to anyone other that internal/required parties.
Best, not so straight way, you could try is get on to their web page, launch the video/series you want and then trace the browser debug logs to find the contentID hoping that its not already obfuscated.
