They have inconsistent acceptable use policies with data transfers or different definitions of public and local network bandwidth? I don't know, I am more confused now.
This is from http://customer.comcast.com/help-and-support/internet/common-questions-excessive-use/#excessive22 stating that the cap indeed still applies for XfinityTV.com which I would assume is on the Comcast local network just like the Xbox service. It was last updated Updated 3/9/2012.
Does the Comcast Usage Meter measure data that I consume from XfinityTV.com?
Yes. XfinityTV.com is an Internet web service from Comcast that you receive using your XFINITY Internet service. Comcast treats its affiliated services the same as it treats any unaffiliated services that you use your XFINITY Internet service to access. All data that travels over the public Internet on our high-speed Internet service (and all data that XFINITY Internet users send to one another using the service) is counted toward the monthly Data Usage Threshold, regardless of the source.
