Regards, Hans Hans, it are indeed only the v4l1 apps like radio, qtradio, gnomeradio and fm from fmtools. Avl is right, mplayer does still work and also kradio. So the trouble happens in the v4l1 compat layer. Symptoms are, that you just have loud static noise and tuning has not any effect. Also no signal and/or stereo detection. fm gives now ioctl VIDIOCGTUNER: Invalid argument. Hermann, I've fixed this in v4l1-compat.c. Can you try this tree: http://www.linuxtv.org/hg/~hverkuil/v4l-dvb If this works (and I expect it will), then I'll post a pull request for this.
