Yes, one gets it always if the tuner does not respond.

Despite other, 55 has the extra dvb-tuner at 0x60 and 112 uses the i2c gate of the tda8290 analog IF demodulator inside the saa7131e chip for tuning.

A known risk is analog TV in overlay/preview mode when the data are directly written to the memory of the graphics card from PCI to PCI/AGP device. Many chipsets don't play nice with it. Another additional risk are Ati and Nvidia binary driver in that mode. Capture mode like on "tvtime" or xawtv so called grabdisplay should be save. I'm also quite sure I never had a crash with mplayer, that can also do dma sound with saa7134-alsa or saa7134-oss if you have no audio cable to the soundcard connected. I can see a analog audio onboard connector. You find more stuff about saa7134-alsa helper apps on the v4l wiki. > Herman, > > What exactly do you want me to do?

Thanks, fairly current stuff on the 2.6.17 should be enough. I have not the slightest idea what should break it on 2.6.21.5. Testing with card=112 should did no harm, I wonder that Werner has at least analog with a stock kernel, but also not even that with recent mercurial. My stuff works. Since I have no datasheets and not even the pinning, someone must help where to look for the physical connection. Usually I would say to Werner try to add .i2c_gate = 0x4b, if analog works and else no tuner is responding. Thought first it might have two, but it is the LR306! It is a bit confusing currently.
