Why do we need to register for a new "appid"?
Given the relationship between the sender and receiver components of Chromecast in JW Player terms being a one-to-one relationship, and with JW having built and registered the receiver application already, I would expect the "appid" to simply be the JW application ID and so this should be defaulted/hidden within the code.
The option to change it would only make sense if you wanted to use JW Player as a sender with a non-JW receiver...
