Signals generated within the DVD recorder itself
are output through composite, component, S-Video or HDMI outputs. It is those "outputs" that are SD.
My current setups use nine recorders with unmodulated RF outputs (passing through signals) and three recorders with modulated RF outputs (outputting a recorder's internally generated signals).
My Panasonic and Funai-built DVD Recorders and HDD/DVD Recorders have unmodulated RF outputs.
My Panasonic VHS/DVD combo recorders have unmodulated outputs upon powerup but any use of the VHS or DVD section or some other operations, e.g., pressing SCHEDULE, switches the RF output to a modulated status until the recorder is powered off. When powered off the Panasonic combo recorders revert to an unmodulated RF pass through output.
See the DVD Recorder sub-forum for more detailed discussions of RF pass throughs and unmodulated/modulated RF outputs:http://www.avsforum.com/avs-vb/forumdisplay.php?f=106
