Want to run my dtv receiver through new digital converter box.

You have to subscribe to DirecTV service in order for it to record. Unfortunately, you have to have the DVR feature activated (with the fee) to record, The hardware will only get DirecTV channels, no analog channels. What you are trying to do will not work.

You will not be able to record local station from a DTV converter connected thru a directv receiver unless there is a a/v input on the directv samsung receiver. Also check the user manual for this receiver if recording from an external source such as a DTV converter box is possible. The answer to seperating the DTV converter box from the directv samsung receiver is possible if your tv has multiple inputs. Try connecting the DTV box to the RF input and the directv samsung box to an a/v input then change inputs using the tv remote. you will need an av cable (yellow/ red/white) for the directv box and a rf jumper cable for the DTV box.
