(PAL I is marked on it) This tuner will not be autodetected! You have to find out, which one it is and you have to set it explicitly with the modprobe options. Open tuner.h from saa7134-0.2.8 in an editor. The first PAL I tuner is tuner=1 TUNER_PHILLIPS_PAL_I. You also can force the PAL I audio carrier (modinfo saa7134) So you can start testing with: "modprobe saa7134 card=2 tuner=1 audio_carrier=6000" The next one is the TEMIC tuner=7, then the ALPS tuner=11 and so on ... Make sure to unload the tuner module after modprobe -r saa7134 too, before you try the next tuner ... if necessary. Good Luck, Hermann
