I would recommend Kodi, it has many plugins that lists a huge load of movie streamer servers.
It also support multiple platform for desktop and mobile too.
The only problem with this app is its quite complex to have it configured. But once it is done, you'll be pleased to its results.
Has anyone used these with Chromecast streaming? I noticed that chromecast is very picky about letting you stream from "not so legal" apps/website It shows th eotion to stream but will never connect (I am sure chromecast has a blacklist on it somewhere)
