I have a Motorola DCH3416 HD TunerDVR and a Samsung remote bn59-00598a and have tried these remote codes 0276 0476 0810 1106 1187 1376 and 064 but can't get the Samsung remote to work Any help?

1376 worked for me on my Atlas OCAP DVR-1056. I couldn't get it to work until I managed to unlock the preprogrammed CBL setting (locked to Pioneer apparently by TW Cable)
