Connecting Digital cable box->DVD recorder->DVD+VCR combo->TV?

Question

I have a situation described below:

I have a digital cable box, a DVD writer, and a DVD + VCR combo.

I made a connection as follows:

Digital cable Antenna TO Cable Box RF-In.
Cable Box RF-out TO DVD writer RF-in
DVD writer RF-Out TO (DVD + VCR) combo RF-in
(DVD + VCR combo) RF-Out To TV

Now I can copy TV programs using my DVD writer.
But I cannot copy anything (not copy protected), I am playing on TV from my (DVD + VCR) combo.

Can anybody help me?

Answer 1

swap the DVD writer with the DVD + VCR.

Answer 2

send cable box to the combo, then send the combo output to the dvd-writer, and from the writer to the tv. Now anything going through the combo can be recorded to DVD before it hits the tv.
