Hello Antii!
I succeed with my tuner Evromedia USB Full Hybrid Full HD!!
$ w_scan -ft -c UA -M
...
tune to: QAM_AUTO f = 474000 kHz I999B8C999D999T999G999Y999 (0:1:43)
(time: 02:59.095)
service = 5 KANAL (Scopus Network Technologies)
service = NEWS ONE (News One)
service = EU MUSIC (EU MUSIC)
service = OTV (SPACECOM)
service = ICTV (ICTV)
service = SONCE (SOLAR MEDIA)
(time: 03:12.851) dumping lists (6 services)
MPlayer and VLC play video and sound, but it's very broken (ugly):
$ mplayer dvb://ICTV
