dvb.o performs it silently.

The bttv package has gone through many many versions and updates - the
same for its own tuner module. The tuner module for the DVB package was
taken over at some intermediate state of the bttv development and supplied
with those special data records describing the DVB frontends. And the DVB
tuner module itself has gone thru several revisions, too.

No! A bttv-tuner.o does not contain any data records for DVB frontends.

The DVB-0.8.2-package only supports the Alps BSRV2 tuner with VES1893
demodulator (regarding DVB-*S*). Your budget card probably has a Alps 
BSRU6 with STV0299 demodulator - no success with DVB-0.8.2.

As said dvb.o detects the current DVB card type and selects, based on that
determination, the correct tuner type. It's not your - the user's - job to
select a tuner type.
