I just bought a Replay tv DVR recorder from ebay . I wanted to know if the d12 box will able to change the channels the proper way . Im tols you need a low speed data port for this or the IRBlast hooked up to change the channels . I was wondering if anyone had them change the channels without messing with it . Some people on the replay site said it wont do it . The reason I got this box Im not going to pay directv 20.00 a month for there box . So to save some money for now . Im going to use replay tv . I also hear that it has commercial skip that way better than TiVo too . I had a direct tv TiVo in the early 2000's and it was costly to pay for service , it had a montly fee for TiVo and to directv as well . I didn't get the replay box as we speak in in process of being shipped tomy house . If for some reason I need a new box from directv that's compatible to change the channels on the replay tv dvr . What boxes from Direct tv are being discounted by them . I would like some one to list all the directv boxes that still a serial and low speed data port if you can . But first Im going to see if the replay dvr willchange channels with the new D12 box from directv .
