MLB Extra Innings Availability for TiVO Customers with Cable Cards

I was told earlier today by Xfinity/Comcast that MLB Extra Innings will no longer be available to any cable card customers; you must have a setup top box from Xfinity to get the MLB package.

This seems crazy to me as I have been a MLB Extra Innings subscriber for over 10 years and had no issues getting the MLB channels (771 to 784) on my cable cards.

Anyone else experiencing this bizzare issue?  Does Xfinity/Comcast plan to fix this in the near future (possibly getting new cable cards for our TiVO boxes)?
