Chris,
I have a Sony RDR-HX715 connected to my BV-7 and I am able to control it partially using the RDR HX1010 codes. Some features, such as the
title lists of recorded programs and the TV Guide have to be activated using the original remote as these codes are not entered in the RDR HX1010 entry.
This is why I think B&O should release to the public the program they use to create PUC lists to allow advanced users to modify and even create their own entries. An IR receiver fitted with a USB connector should also be provided to allow the program to read codes from the original remote. The user will be then able to map these commands to Beo 4 or 5 keys.
Good luck,
Jean
