I have not been able to get the Xfinity TV app to view any programming on my iphone 5 /ios6. I keep getting the "sorry. weve experienced some difficulty playing your video" message. The same programming works when I am using my laptop and the Xfinity web site to view it, so I doubt the problem is with my wifi setup. All the other feaures of the iphone app seem to be working. A Comcast support rep told me there was a problem with my operating system and tried to give me the phone number for Microsoft to resolve an iphone/ios problem. I have already deleted and reinstalled the app.
The manual DNS entries fixed my problem at home. The problem is with the iphone 5, or my router, or the xfinity app, or my ISP (comcast). Maybe someone from comcast can help.
Did you redo the setup on the new phone when you got the new one??? Go to settings and to the app, now sign out of the app, now clear all the data, cookies cache, and the data in the app. Now log back in and try it. Also I don't know if you are aware you can only have 3 devices on your account, your pc being one of them so you have two phones one the old one the new do you have anything else using the app? If you do theres your problem. To see what you have assigned to your account click the watch tv tab top of this page, then bottom right next page click the little wheel. on that next page look for cable boxes and devices when you go in there you can delete the old phone you were using and then when you synch up with the new one it should work, if that was the issue.
So I have been jumping through hoops for a couple of day and followed some very length instructions sent my a rep for Comcast/Xfinity...in the end I found and optiions to manually change the channel line up. The app preload a "DAC" line up based on your username/account...if you search for you home zip code then choose save in the upper right corner everything should start to work fine...
