A glitch in AT&T’s U-Verse TV service has bloggers buzzing. According to a U-Verse users site, when the company first started rolling out the service, every set-top box it deployed was a DVR box. The company soon changed that practice and began giving customers only one DVR box; additional outlets in the home were outfitted with a non-DVR set-top. But some users quickly discovered that the additional boxes were basically DVR receivers with the hard drive unplugged. So, they plugged the hard drive back in and, surprise, had DVR service on all sets. Here’s the full “Hacking Your Set Top Box” article on the users site, and what Engadget has to say about it.
