I've tried your fix, and it didn't work for me. I've reset my STB, router, DVR; I've added all channels then deleted them. Channels that show up in Fav aren't selected - that is, when I go to remove the heart or use Options to go to Favorites, then ADD - the channel is not selected - but still shows up. I contacted Verizon, and was told that it has to do with my old router, and for only $85 more per month, the problem will be fixed. So - Verizon has left me with old equipment which they won't upgrade unless I pay them over $1000 more per year.
3 times already and whenever I add my favorite channels and block over 20 channels hours later my favorites are gone and block channels are now unblocked! this has never happend before. This has been a constant struggle for me now.
A agent suggested updating my box (installing a new one...I have the quatum box for 2 years) but I want to check here first. Any suggestions?
