Hello and thanks for the help

To many times I do the same error and ask a question with some lack in
details.

I have a stereo satellite receiver and a stereo TV and a mono video
cassette, so I want to be able to enjoy watching/listening in stereo but
record in mono but have both L+R lines. I never do that before and it look
to me if I use 2 resistor in series to join the stereo I will destroy the
stereo signal.

I know when you want to separate a dc sources or join them you can use a
diode/s but in this case it looked to me to distorted and not acceptable. so
AC signal give you an headache... furthermore you don't want to kill the
sound.

I think I will adopt the buffer idea and try it.

Thank you all for you help!
