I'm using Chrome 43.0.2357.65 m, Addblock disabled for giantbomb.com, im a premium member though anyway. My Problem is, i can not watch half the videos while others work perfectly fine. For example: i can not watch the Black Mesa Unfinished (the video simply never does start to play), but the Witcher QL works perfectly fine. On the same not, i can not watch any streams anymore, they have the same problem as the Black Mesa video, there's no playback.
I started to notice this when GBEast did their third Castlevania stream, couldn't watch that, and the following UPF either. As far as i can tell before then everything worked perfectly fine.
