Time Warner Cable is notifying its customers in Charlotte, N.C. to prepare for the transition to all-digital cable television service which will be complete by the end of this summer. Further south, San Antonio customers can swing by their local cable store and pick up Time Warner Cable’s new terabyte DVR, which can record up to six different programs at the same time and store six times more content than current DVR boxes.

The changes are part of Time Warner Cable’s Maxx upgrade program, which will vastly increase broadband speeds and deliver an all-digital experience to current customers in cities where the upgrade is underway.

“The bad news is you need boxes on all of your televisions,” writes Stop the Cap! reader Susan in Charlotte, who had to pick up three new set-top boxes to keep cable television running in her home. “They are going to move channels in groups to digital-only service over the summer so you will gradually lose your cable television unless you have a box on every set.”

The transition begins in early June and will last into August. Time Warner is offering customers a digital adapter to bring back the digital-only channels on older televisions. Those ordering before Dec. 10 will get them free until Aug. 11, 2016. After that, they will cost $2.75 a month each.

“Weren’t they going to rent these things for $0.99 a month,” asks Susan.

Indeed, when Time Warner Cable unveiled the small devices, they promoted the post-promotional price as $0.99 a month. Earlier this year, the price jumped to $2.75 without explanation. Standard set-top boxes can cost $7 or more a month, but are equipped with an on-screen guide and can access on-demand shows that the digital adapters cannot.

In San Antonio, customers can ditch their old DVR for a major upgrade with more storage space and a better user experience, or so the company claims. Current DVR users should be able to swap out the equipment by bringing in their existing box for an exchange. Be aware all recorded shows will be lost.
