Hi Dave,
I have the Comcast DTA with a Series 2 Tivo as well. I had some reliability
problems with it at first but now it seems pretty solid, albeit slow. What I
did was to take the remote IR reciever from the DTA and the IR blaster from the
Tivo and taped them together. Lens to lens. Then I wrapped the two with
aluminum foil. The foil will reflect any IR light inside and block anything
from outside. Sure it's ugly, but I hid it behind the TV so you and I are the
only ones who know about it.
My primary Tivo is the HD model with a cable card and it works great since it
doesn't need the DTA. I get my extended basic from Comast, but to keep them
from getting another penny out of me I build my own very simple HDTV antenna
for HD.
YMMV
Chris
