TV tunes ok but my DVB cards won't tune
Hi all, I hope this is the right place to try and troubleshoot my DVB setup. I have a Conexant based tuner that used to work with the cx88 driver and an Avermedia USB tuner. I have moved house and can't get either of these cards to tune using the scan or dvbscan utilities. Mythtv is able to pick up the channels when it scans but it can't tune to them later when I try to watch live tv. As it tunes, I briefly see mythtv reporting signal strengths around 40% My TV is using the same antenna (with a splitter) and it picks up the channels and reports 30-33% signal strength and 100% signal quality. Also, I'm not sure I have the right channel file as I live in country Victoria and the closest city is Melbourne so I'm using that file. I would expect to at least tune the major channels. Is this just a case of needing a better antenna or is there something else I can try? (I am already using a signal amplifier at the wall socket.)

Is this just a case of needing a better antenna or is there something else I can try? (I am already using a signal amplifier at the wall socket.) An amplifier at the wall socket is suboptimal. For weak OTA signals, you want a low noise figure ( 3 dB ) pre-amplifier located as close to the antenna as possible - before the splitters, long cable runs, and wall plates - so you can maintain as much of your received SNR as possible. (In the US Winegard make some good units.) Also be aware that over-amplification can overdrive the tuner front ends causing intermodulation products that show up as noise and degrade the SNR. You may find the information here useful: http://ivtvdriver.org/index.php/Howto:Improve_signal_quality once ivtvdriver.org comes back up. It seems to be down right now.

I cannot tune with this card and STR/SNRA is very bad compared to my Technisat SkyStar 2 pci card, connected to the same dish. I have this card and are willing to run tests, tested drivers etc to make this work. I currently load the module saa7134 with options: card=169 I enabled some debug parameters on the saa7134, not sure what else I should enable.

See http://osdir.com/ml/linux-media/2009-06/msg01256.html for an explanation. For quick confirmation check if you have 12V - 20V DC going to your LNB. The relevant lines of code is in ~/v4l-dvb/linux/drivers/media/video/saa7134/saa7134-cards.c: case SAA7134_BOARD_VIDEOMATE_S350: dev-has_remote = SAA7134_REMOTE_GPIO; saa_andorl(SAA7134_GPIO_GPMODE0 2, 0x8000, 0x8000); saa_andorl(SAA7134_GPIO_GPSTATUS0 2, 0x8000, 0x8000); break; Hi thanks for the hint. I changed it to the following: case SAA7134_BOARD_VIDEOMATE_S350: dev-has_remote = SAA7134_REMOTE_GPIO; saa_andorl(SAA7134_GPIO_GPMODE0 2, 0xc000, 0xc000); saa_andorl(SAA7134_GPIO_GPSTATUS0 2, 0xc000, 0xc000); 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. You can see this by looking at the i2c traffic addressed to 0x1c (demodulator) and 0xc0 (tuner). Attached is a dmesg trace from my working SAA7130 based card.
