Per Humbled Survivor:
The only solution I have in sight is to buy an HD TV for hundreds of
dollars.

If you don't need a huge screen, think more like $130-$200 for something
in the twenties size-wise.... at least that's what I saw today at HH
Gregg.

OTOH, I wonder if the cable supplier has done something proprietary to
the signal and you would need some sort of box (which might make the
converter work) even for a new TV...
