Hi Steve,

The output of Tivo's modulator should be perfectly acceptable (as much as
an
RF output can be) because most equipment tends to use the same modulators
made by Alps.

In what way is it atrocious ?

It could be that it is just set to the wrong channel an dis on a
"taboo"
channels which is one that suffers from interference by a
channel -9, -5,-1,+1,+5 or +9 away from it.

Take a look at http://www.kat5.tv/taboo.html for
more info. If the taboo
calculator isnt working try a few hours later. It is hosted on some free
server in the states and occasionally breaks for a while :-(

Another possibility is that Tivo's modulator is being overloaded by too
strong a signal being fed into it.

You can quickly prove if overloading or a Taboo channel are causing
problems
by removing the aerial input to TV and seeing if its output goes clear. (At
this point all other TV signals should be missing from your TV. If they
arent then there is something strange going on with your RF distribution
system and any other modulator you use in its place will almost certainly
be
affected as well

Unless the modulator cost an absolute fortune I can safely say that its
output will be mono. To get stereo modulated audio requires a nicam encoder
and these dont come cheap. The RF output of all domestic VCR's and Set Top
boxes is mono which is one of the reasons people use KAT5 to distribute AV
around their homes.
