From the spec sheet:
SR7002 is equipped with high quality video conversion. It can
convert the Composite signal up to S-Video/Component and
S-Video up to Component; as well as down conversion. But it
doesn't stop here. All analogue signals can even outputted via
HDMI. To avoid compatibility problems in this process the
SR7002 incorporates I/P conversion. This means each signal
will be converted from interlaced to progressive. All this
allows you to connect a high quality video cable between the
SR7002 and the display sending all your video signals via one
cable to your display. In order to avoid synchronization and
eroded video quality problems, the SR7002 has a high quality
video converter equipped with digital video processing
consisting of 4H line memory, time based corrector, a triple
10-bit DAC, filed locking, VCR detection and anti aliasing
filtering. The SR7002 provides you the highest analog quality
from all sources connected via a single component connection.
So it does seem that one can do what I want - output all signals via components to the TV - assuming of course that the DVD is connected via component cables
