have an RCA DVR40 with two IC baked drives with total capacity of 191 hours recording time. However the modem has failed and I cant make PPV orders anymore, I get the ext 733 error. I have a second RCA DVR40 I purchased used and it works fine including the modem. Can I move my IC baked drives to this DVR and do a clear and delete, and then run guided setup, or are the drives married to the first DVR. Any avvice would be greatly appreciated.
