how do I add more favorite shows ro my iTV, XFinity-Comcast TV equipment. I used to be able to add my favorite shows to a list that saved them for me on my comcast on demand, I do not have xfinity xi nor do I want it, I just want to know what happened to the option where U could save favorite shows & add them yo a list. so when I went to that list picked the show, it would come up on my tv with all the previous and new ones.
