With the surge in digital television, soon those of use that like to
distribute and mix RF into the house coax will have lost that nice
ability, until an affordable digital video modulator comes along. I've
been scouring the net looking if this is available yet, but haven't seen
it. (and no, I don't want to be switching between analog and digital
tuners......it's too confusing for the family) I'm trying to make it a
turnkey
operation, so feeds like surveillance cams, off-air signals and other
video feeds can all coexist on the same wire and be switched cleanly via
the digital tuner.
Has anyone seen an affordable digital modulator yet??

Why ? just about any digital TV still recieves analong signals. It is
channel XX.0 in the tuner's lineup whereas the digital channels are XX.1
.2 .3 .4 ect.

My digital converter does NOT pass analogue signals nor does it receive
xx.0 channels. When I try xx.0, it shows xx.1.

The feature is called "analog pass-through" and it is only present on
some DTV converter boxes (possibly a minority). You might get some
analog reception even on those without it, but that's just leaking
through or being picked up by the cables. They won't tune to the
analog channels.

For most people this won't matter after the switchover.
