Can I connect components which have earlier versions of HDMI?

Yes, because HDMI is backwards-compatible. This means that components
which have earlier versions of HDMI (such as HDMI 1.1 or HDMI 1.2)
will perform correctly when connected to the HDMI 1.4 inputs or outputs
of the unit.
If your DVD player is equipped with HDMI 1.2a, the HDMI connection
will permit the transmission of 1080p (high definition) video signals.

Which is the best way to rescale the picture?

When using legacy components that require picture rescaling, it is better
to use the monitor scaler to handle any picture resizing. You should try
to use only one scaler in the system, so keep your DVD player set to
480p or 1080p. A 480p signal will be rescaled by the monitor and
a 1080p signal will be seen by a monitor with 1080p resolution as a
native signal.
Some Blu-ray and HD-DVD discs have been recorded in 1080i. These
should not be scaled, but are best left to the monitor to interpret into an
appropriate format for the screen.
Will the HDMI digital output improve the picture quality from old
analog sources?
Analog picture sources from legacy units begin by being less good than
digital signals, and while the RSP-1572 will translate them into a digital
format, the final quality will be constrained by the original source, and
the choice of connection (Composite or Component). The scaler cannot
correct for low resolution signals and will not improve inherently poor
picture quality.

Why does the HDMI connection sometimes not give a picture?

Although it is simple to use, the HDMI connection is actually a highly
complex electrical circuit, and within it is a security system called HDCP
(High Definition Content Protection). In some circumstances pictures
may not reproduce, or may not reproduce properly, due to the action of
DRM (Digital Rights Management) or the 'handshake' between the two
connected units. HDMI cables contain circuits that exchange a 'handshake'
signal several times a second, designed to maintain the integrity of the
transmission signal and to prevent attempted unauthorized copying of
copyright material. However, these 'handshake' signals can be disrupted
for several reasons. If problems persist, consult your Rotel dealer.
