As you can see in the screen grab above, the Major League Soccer videos do not work in Ubuntu. At the beginning of the 2010 season it was announced that MLS would start streaming live video feeds in much higher quality than in previous years. Along with the news, came the horrific fact that the newly revamped & beautiful website was going to use Microsoft Silverlight. I really didnt think much about this, because the Vancouver Winter Olympics website also used Silverlight for videos. I simply installed Moonlight, the linux equivalent, and I got to see the winter olympics highlights.
Major League Soccer did not work, and it has not worked since March 2010. A recent chat with Moonlight turned up some info. The problem is not DRM rights, but a codec issue with h.264 and this will be resolved sometime in November. When? Dont know. Will us Major League Soccer fans get to watch streaming games again soon before the playoffs and season ends? Dont know.
You would think a young league like MLS would strive to provide easier access to videos for its fans. Lets hope things are about to change for the better.
