I changed it to the following: case SAA7134_BOARD_VIDEOMATE_S350: dev->has_remote = SAA7134_REMOTE_GPIO; saa_andorl(SAA7134_GPIO_GPMODE0 >> 2, 0x0000c000, 0x0000c000); saa_andorl(SAA7134_GPIO_GPSTATUS0 >> 2, 0x0000c000, 0x0000c000); break; I now get the same SNR as on my skystar2 card, signal is still indicating 17% where as the skystar2 would show 68%. At least I'm getting a LOCK on channels :) Thanks! > > Looking at your log, at least the demodulator and tuner is responding > correctly.
