This is the future of DIRECTV: It's all RVU, and it's smaller than you imagined. Yes, that's an iPhone on top. C31 First Look This is an incredibly small box. It only works with the HR34 but it provides full DVR functionality with zero fan noise. Even pause live TV! I'd like to thank the hard working C31 test team, who really came through on this little box. The C31 is only available in limited areas at this time. Please note that some DBSTalk.com testers and staff members may have received free equipment from DIRECTV or its partners for the purpose of evaluation and testing.
