Is recording with my VCR still possible now that I have a Motorola DCT3416 DVR and a Comcast HD signal?

The cable guy connected the coax cables in this order: 1) The cable into the house is connected to RF IN on cable box. 2) RF OUT on cable box is connected to VHF/UHF IN on VCR. 3) VHF/UHF OUT on VCR is connected to CABLE IN on TV. And he connected HDMI OUT on the cable box to HDMI IN on the TV. Viewing TV when I select the HDMI input works fine. Recording with the DVR works fine. However I'm not able to view TV nor record TV with my VCR when I select the cable input (Again, the cable input is where the coax cable finally ends.). Should I be able to view TV and record TV with my VCR using the signal on the coax cable and the aforementioned connection configuration?
