I changed the value ".demod_address = 0x19" by ".demod_address = 0x10" 
and resolved

Attached list of changes I made.


Results:

Analog TV can be seen, but no sound.
If I use xawtv or VLC the image is in the middle of the screen and there 
are stripes, as if interference. If I use tvtime will look good.

Digital television: not tune any channels with w-scan or gnome-dvb-setup.
But with the latter, it captures 2 weak signals, but I can not know 
which is.
Under windows also capture 2 channel and I'm in a place where the signal 
is low.
I'll try to have more signal strength.

If I run dmesg after scan channels I get the following:

[ 3474.858537] mb86a20s: mb86a20s_set_frontend:
[ 3474.858541] mb86a20s: mb86a20s_set_frontend: Calling tuner set parameters

[ 3475.182829] mb86a20s: mb86a20s_read_status: val = 2, status = 0x01

When detected signal with gnome-dvb-setup, sometimes gives this warning:

Message from syslogd@linux at May 4 01:48:38 ...

Thank you very much,

Alfredo
