  We summarise the results and achievements of integral-field spectroscopy of
early-type galaxies, observed as part of a survey using both the SAURON and
OASIS spectrographs. From the perspective of integral-field spectroscopy, these
otherwise smooth and featureless objects show a wealth of structure, both in
their stellar kinematics and populations. We focus on the stellar content, and
examine properties on both kiloparsec scales with SAURON, and scales of 100's
of parsecs with OASIS. These complementary studies reveal two types of
kinematically distinct components (KDCs), differing primarily in their
intrinsic sizes. In previous studies, KDCs and their host galaxies have
generally been found to be unremarkable in other aspects. We show that large
KDCs, typical of the well-studied cases, indeed show little or no age
differences with their host galaxy. The KDCs detected with the higher
spatial-resolution of OASIS are intrinsically smaller and include, in contrast,
a significant fraction of young stars. We speculate on the relationship between
KDCs and their host galaxies, and the implications for young populations in
early-type galaxies.
