I've been using TV Everywhere Beta for a while now, and I am still having issues with certain channels like Diy. These channels work for a week after adding TV Everywhere as a source, but after that week, the only way to make the channel work again is to delete TV Everywhere as a source and then create the source all over again. It seems as though the issue is that I am automatically logged out by Diy and other channels that are owned by Discovery, Inc. after 1 week. Restarting the computer does not fix the problem either. The source must be deleted and readded before everything works again.
My cable provider is HTC Digital Cable.
