Hello All, I was considering making the switch from Comcast to DirecTV and since I already have a series 2.5 with a lifetime subscription I wanted to make sure that it would work with the DirecTV receivers. Would it work just like your standard cable box via serial cable or IR cable? Also, I managed to pickup an RCA DVR80 DirecTivo unit at a yard sale for $10 this past weekend. Will this unit continue to be supported by DirecTV for the foreseeable future? I know that they have their own version of DVR software similar to the Comcast DVR software. Thanks!
