Hm, the LNA has such a high gain... i dont think that a additional amplifier
will give improvement. Please do the following: set the options debug=1 for
the modules tuner and tda827x. and send me the kernel log of driver load
and tuning attempts.
The card i had in hands had no sensitivity problems. But is was a 'early
sample' You might decide to play with the antenna switch config entry
in saa7134-dvb.c.
