Posted this over on Rivals as well. Unfortunately Comcast seems to have half-assed it and implemented their usual plan to make things as difficult and circuitous as possible. They are only available via the website, not the Xfinity iPad or Xbox apps (because...why would folks want to watch a game on their actual television). I have a sneaky suspicion that Comcast customers are suffering through this fiasco because Comcast gets to keep all the web-site ad revenue by forcing us to go through their content portal. To access the feed you need to go to http://xfinitytv.comcast.net. You should now see the Pac 12 network logo listed in the "Watch Live now on Xfinity TV' section. Unfortunately this is where you get in to the half-assed part of the implementation. When you click on the Pac 12 logo it takes you directly to the National feed. I don't see any method of selecting the regional feeds available via the site navigation. I was able to find the regional feeds but, only through a post on their forums (good job Comcast, its not like most people are going to want to view the regional feeds rather than the national feeds or anything...particularly since the cable companies were the ones pushing the regional model so they could get more money off ad sales). Here are urls for the regional feeds: National - http://xfinitytv.comcast.net/live/network/pac12net work AZ: Phoenix and Tucson - http://xfinitytv.comcast.net/live/network/pac12net workarizona CA: San Francisco - http://xfinitytv.comcast.net/live/network/pac12net workbayarea CA: Los Angeles - http://xfinitytv.comcast.net/live/network/pac12net worklosangeles CO: Denver - http://xfinitytv.comcast.net/live/network/pac12net workmountain OR: Portland and Eugene - http://xfinitytv.comcast.net/live/network/pac12net workoregon UT: Salt Lake City - http://xfinitytv.comcast.net/live/network/pac12net workmountain WA: Seattle and Spokane - http://xfinitytv.comcast.net/live/network/pac12net workwashington Also, to access the feeds you need to have a browser plug-in for Microsoft Silverlight installed. I ran into an issue when I tried watch the feeds. Comcast's site would tell me I needed the plug-in, but when I attempted to install it in either Chrome or Firefox the installer would give me a message that the plug-in was already there (which is likely since those were my primary browsers). I couldn't get around the issue since the Comcast page kept saying I needed the plug-in and not recognizing that it was there. I got around the issue by opening one of the feed pages in IE which I never use. When I used IE the plug-in successfully installed/updated. Once I got the feed working in IE it started working in my other browsers as well. I'm not sure if it was a Comcast issue, or a Microsoft plug-in/installer issue.
