I just had mine set up today... it was the installer's second one, and he learned quite a bit from my setup. With the installation I replaced an HR10-250 in my kid's room with an HR23, and an old Philips SD DirecTiVo in my workout room with an HD receiver (no need for recording in there). MRV, VOD, and Music/Photos "work," but much more slowly than when I used powerline adapters between my living room HR21 and bedroom HR23... VOD was extremely slow using DECA, and MRV took quite a bit more time to "cue." For now, my living room and bedroom DVRs are connected via powerline again, while the other two are connected via DECA. Has anyone else had such an experience? Could there possibly be something wrong with the installation? Thanks in advance. [EDIT] Changed subject to reflect issue better (after much troubleshooting).
