WideVine DRM Sample Video Stream
The only ones I could find are here: http://www.widevine.com/demo/index.html
Stream 1: http://commondatastorage.googleapis.com/wvmedia/sintel_main_720p_4br_tp.wvm
Stream 2: http://commondatastorage.googleapis.com/wvmedia/starz_main_720p_6br_tp.wvm
I've played these streams on a Windows PC, while running Wireshark and the player is certainly exchanging data over SSL with Widevine/Google's DRM service at staging.shibboleth.tv (216.239.32.27)
