I just signed with Comcast and I'm really interested in getting rid of the X1 dvr. Coming from Dish. I'm not fond of the interface and especially the small 500gb hard drive. I'm trying to calculate costs to see if Tivo is the way to go, or just stick with the X1. Questions to Comcast users. I am getting charged $10 a month for "HD Technology Fee". Does this go away if I buy the Bolt or do I have to keep paying for HD content with Comcast?
