The very next message on that thread was a post by me relaying 
information from Mike Krufky to the effect that what Leonardo did should 
not have been needed, that the required changes have been in v4l-dvb for 
over a year by that point.  I had requested that he at least try v4l-dvb 
tip.  Leonardo replied that he would try it, but I don't see any other 
reply.

So from where I'm sitting this is still unresolved.  Somebody with one 
of these tuners needs to verify that v4l-dvb tip works properly.  I 
can't do this; I don't have that hardware here.  (Even if I did I'm in 
the USA so I also don't have a compatible signal source with which to 
test this.)
