Actually some time ago d2h updated some hd stb box 2011 for recording facility but due to some issue/problem in new software they stopped the update process in remaining box.After the software update,recording facility will get enabled through external devices i.e by using pendrive.The charges for recording is Rs.199 for one time activation and Rs.30 monthly subscription charges.
Still many hd stb box 2011 pending for software update.As soon as bug-free software will realese all hd stb box will get updated with recording and dolby digital enabled software with fast epg,etc...Currently no sign from d2h side regarding any testing for the same.So it may take some more time.
