NO. There's no justification for this fee when they are already charging for equipment rental. It sounds like this fee would be in addition to the current fees, since renting a cable box already costs more than $7.
If they decide to implement it, they can take their buggy DVRs back. For this price, I would much rather buy a TiVo or build a Windows Media Center box and have something that works and can store more than a few hours of HD content. A nice side benefit would be having access to modern software with a proper keyword search interface and numerous other features that are still lacking after 5+ years of development.
