Airplay not supported for NBC with the ios7 upgrade

Upgraded to ios7 for my iphone 4s and when trying to view NBC shows, error message is received indicating that Airplay is not currrently supported. Airplay is/was supported for my ipad 3 for NBC, but the upgrade to ios7 on the iphone 4s seems to be problematic and I cannot view the shows but I can only hear them (no visual/only audio is received).

Is there a fix for this problem? I am really disappointed that this is happening since all the other channels work, except NBC.

Please advise.
