mezitim jsem to taky zjistil. Ty velke titulky STEREO se bohuzel tykaly
jen FM radia, TV tuner je mono jako poleno.

:-O to jsou mi cenne zkusenosti. Muj hlavni problem totiz je, ze tvaudio
se nekdy chyti a nekdy ne, a pak pomuze jen vystoupit a nastoupit. A to
mohlo byt kvuli tomu, ze jsem mel v modules.conf napsano "bttv
post-install insmod tvaudio", coz presne odporuje tomu, co rikas ty.

chci vsechno (modules.conf, .xawtv, lsmod a co jeste by mi mohlo pomoct)
a predem dekuji.
