The whole house suppressor specified by w_tom would not have protected my
equipment as it is only for power, and does not cover the phone line. I
would have needed protection on every line coming into the house. (I do
now.)

Again you have posted by not knowing about the 'whole house'
protector installed where every phone line enters a building. You
have assumed and only assumed the surge entered on phone lines because
phone appliances were damaged. Most who forget how electricity works
(as taught in primary school science) make that assumption. Does a
surge enter on phone line, damage the TiVo, then stop? Of course not
- as made obvious even by what is taught in elementary school science.

Surges are electricity. That means a surge flow through everything
in a path from cloud to earth. To be damaged, the appliance must have
both an incoming and outgoing path - again taught in primary school
science. That TiVo, et al damage is typical of surges that enter on
AC mains and obtain earth ground destructively via phone lines. Why
to ground on phone lines? Again, Joe did not know about the 'whole
house' protector installed for free by the telco on every residence.
And Joe forgot what is required to have surge damage. First a surge
must flow through everything in that path. Both an incoming and
outgoing path must exist in that TiVo. Surge did not enter on phone
line, cause damage, then stop. Surge did not ignore the telco
installed 'whole house' protector. And yet Joe had to make both
mistakes to know how TiVo, et al were damaged.

Cable TV is earthed without any surge protector (if installed by the
newer and more responsible cable companies). Telco installs a 'whole
house' protector at every subscriber interface (the NID). Utility
wire that is most often struck by lightning is also the only utility
typically without any protection - AC electric. Joe did not even know
about those other earthed protectors.

Joe made conclusions using assumptions. He did not even know of a
'whole house' protector installed free by the telco. Why not? That
basic knowledge is even required by National Electrical Code and FCC
regulations. Why is Joe so critical while not even know of a
protector even required by code? Joe sees contradictions because Joe
did not first learn the technology.

Why does the telco install a ‘whole house’ protector – not install
plug-in protectors? Because telcos spend less money on a protector
that actually does provide surge protection. Typical reason for that
TiVo damage - incoming on unprotected AC mains; outgoing to earth
ground via the telco installed 'whole house' protector that Joe did
not even know exists.
