HDMI video is identical to DVI, so "From a user's perspective, an HDMI display
can be driven by a single-link DVI-D
source, since HDMI and DVI-D define an overlapping minimum set of supported
resolutions and framebuffer formats to
ensure a basic level of interoperability."
The reverse is probably generally true, with exceptions that don't apply to us
garden variety folks, except for HDCP, a
later DRM. A rights protection source will require two way communication that
DVI doesn't support.
I've driven a DVI TV off the HDMI output of my notebook using a HDMI to DVI
cable and an audio connecter.

I think that's not true. DVI to HDMI video is just mechanical connection. Audio
is separate.
