Leonardo:

I'm not the expert on DVB tuners innards (I just maintain a bridge 
driver, pvrusb2, which can use them as supplied by v4l-dvb).  And I 
don't have an HVR-1900 with which I can test, being that I'm in the USA.  

However I asked the person (Mike Krufky) who knows about these, and he's 
a little puzzled by exactly what software revisions you are running.  
Apparently this setup has been supported in v4l-dvb for over a year.  
He recommends building what is in v4l-dvb tip (Mercurial repository):

Alternatively the needed changes are definitely here:

http://kernellabs.com/hg/~mkrufky/tda8295/

You mentioned a 2.6.32.2 kernel in your message, and I would presume 
that if the needed changes have been in v4l-dvb for at least a year, 
then they should also be in that kernel version anyway.  But try 
building one of those v4l-dvb repositories against your kernel and see 
if that makes a difference.
