Domnivam se, ze v pripade tohoto typu karty je jaksi bttv mimo. O funkcnost
teto karty se stara ati.2 driver pro XFree 4.0.2 ze stranek linuxvideo.org
O zvuk se stara chip rady MSP34xx a tady bude mozna zakopany pes. Pro
evropskou verzi karty existuje verianta chipu MSP3415 (pro evropske zvukove
normy).
Kdesi v hloubi internetu, konkretne v mail archivu livid-ati na linuxvideo jsem
narazil na tuto zpravu:

Hi, 
I have written code for MSP3415D (used in Europian version of AIW). You can
get it here: http://web.redbox.cz/IvoK/MSP3415/r128_drv.o (my sources
http://web.redbox.cz/IvoK/MSP3415/r128_src.zip) Driver detects type of MSP
chip (3415,3430) and use the proper one. There is also support for NICAM,
but it's not verified (I'm receiving terestrial PAL D/K1 only). Notes: - Xv
Driver development for XFree 4.0.1 seems to bee dead. As soon as drivers for
4.0.2 (ati.2) will bee functional I'll move MDP3415 to it. - MSP34xxD has
not MODUS register => mode changes (stereo, mono, bilingual) cannot be done
automaticaly by MSP itself but have to be done programaticaly. It implies
periodical checking of mode -> this requires to make new program thread. I'm
not so experienced in linux programing to do it. I hope somebody helps me
with this when ati.2 drivers gets finished. Now, manual channel reselect in
xawtv is needed to accept mode change. - When 6.5MHz carrier is detected
SECAM_L is used in case of SECAM broadcasting, D/K1 is used in case of PAL
broadcasting. NICAM-D/K and D/K2 are not recognised yet. Ivo.

Dalo sice praci upraveny driver najit, protoze odkaz jiz neni funkcni (
nalezeno nakonec na http://mujweb.atlas.cz/www/r128/MSP3415/r128_drv.o )
Odpoledne to vyzkousim a dam vedet.
