Google Chromecast just got an update with additional apps to work with it. The update automatically kicks in once you run the device on your TV.
Just saw the update yesterday morning after setting up the TV in my room. The update took quite a while and hanged up several times until it was completely downloaded and installed (I just pulled the plug and re-insert it every time the update hangs up).
The new apps include podcast channels, online TV networks and cloud media services — Red Bull TV, Plex for Android, Viki, Real Player Cloud, Avia, Revision3 and BeyondPod.
All, except one, are free to download (Plex for Android costs Php226). This puts the number Chromecast apps to 9 (initially YouTube and Play Music).
