--- Comment #1 from Erich Hoover ehoover@mines.edu 2012-08-31 21:02:29 CDT --- I've found a test site for PlayReady that may help solve this problem (http://playready.directtaps.net/smoothstreaming/). This particular site is convenient because it shows the exact same video both with and without encryption, and the unencrypted video plays perfectly! The encrypted one does not behave the same way as Netflix (clicking play does nothing in the UI), but it does generate a lot of the same spew in the console.
