OOoooohhhh yeahhhhhh!!!
Goodd Herman, everythink works now in ANALOG mode!! Thanks a LOT!!!
i write here some tips to other user that could have my problem
So... Pinnacle 310i is very different from 300i here thereis an image :

According to Hermann : [tda8290 is the IF part of the 8275a silicon 
tuner on your board
integrated in the saa7131e chip. No tuning this way. The current code is 
even assumed
to be able to detect the difference between a tda9887 and tda8290, also 
between the
older 8275 and the hybrid 8275a silicon tuner, which should result in a 
tuner line in
"dmesg" with tda8290/75a registered. No chance without it!]

Okay ..GO GO GO!!!!

It's a good idea recompile your kernel with this tips:

Device Driver --->
      Multimedia Devices --->
          <M> Video for Linux
              Digital Video Broadcasting Devices --->
                  [*] DVB for Linux
                  <M> DVB Core
	I2C support  ---> 
	   <M> I2C support  
		 <M>   I2C device interface


[If you want to use tvtime don't forget to enable RTC(Real Time Clock) in APM section]


Now to get this card working under linux you must get a v4l-dvb 
mercurial kernel/driver from linuxtv.org.
To get from cvs ...do :

cvs -d :pserver:anonymous (at) cvs.linuxtv.org:/cvs/video4linux login
[at password press enter]
cvs -d :pserver:anonymous (at) cvs.linuxtv.org:/cvs/video4linux co v4l-dvb

go to v4l dir and type

make merge-trees
make
make install

reboot your machine!

after you logged in :

modprobe saa7134 card=77
and look at your dmesg.
and everythinks gonna be allright!

Here some tips from hermann (without him i was lost! Still thanks)

After modprobe -r the related modules first do "modprobe tuner debug=1".
Then you can try "modprobe -v saa7134 card=77 i2c_debug=1" to see if
hidden options slipped into your modprobe and where the i2c
communication fails. DVB-T doesn't work yet on the card and also tvtime
doesn't support it.

If in dmesg there is a i2c_core eeprom read error :

If you have load saa7134 and dbv you should stop to
load saa7134-dvb in favor to get analog tv with card=77 first.
Attempts of digital tuning might cause i2c breakdown on the card, also
using the old code of the 8275 not _8275a_ silicon tuner. That's why I
asked for a _cold_ reboot and then try with card=77 and mercurial.


If errors persist  try to change pci slot, because also an instable PSU 
has caused
similar troubles already.
