I have read that before when looking for tuner types, but going back to it again has put me on the path to fixing the problem. The problem on FC2, even though it was working ok when I first installed the TV card, and tried it with Xawdecode, is to do with IRQs. Initially both "video" and "audio" parts of the card shown in lspci were at IRQ 10. Now for some puzzling reason they are both at IRQ9. As suggested in the HOWTO I ran xawdecode -hwscan, and miraculously along with the output, the bttv, and dependent modules loaded. Also the IRQ of the video part of the card was changed to IRQ10, verified in lspci -v. Next under the "autoloading the modules" paragraph, I just added the line. pre-install bttv to /etc/modprobe.conf. On the bootup text this showed up as a bad line by modprobe, but starting Xawdecode from it's desktop icon, it started ok, and I have TV. I have no idea where this "pre-install" command comes from, as it's not in the man pages for modprobe, or modprobe.conf. Be that as it may. My /etc/modprobe.conf for the bttv stuff now looks like this. alias char-major-81 bttv (added when card was detected by Kudzu) pre-install bttv (this appears to run when xawdecode is opened) options bttv tuner=38 (added by me as tuner is detected as "4". No tuner) install bttv /sbin/modprobe tda9887 port2=0 pal=I; /sbin/modprobe --ignore-install bttv (this line installs tda9887 with it's options before bttv, which is a tip I saw on a forum post specifically for FC2) Just for info. The "port2=0" option is try if you can't get any sound. this works for me. I'm in Northern France, and this fixes the sound for the French SECAM channels, and for the Belgian PAL channels. The "pal=I" option, and that's an upper case "i", fixes the problem of getting no sound for the UK channels. Another option to be added the "options bttv tuner=x" line if you have low signal strength on the audio is, "automute=0" . This works on FC3, Kubuntu, and Debian Sarge, but not on FC5 for some reason, and I havn't set the option on FC2 yet, but expect it to work. FC5 has Kdetv available, and the config file for kdetv in .kde/share/config shows automute as false, but doesn't seem to work. I installed Xawtv from Axel's repo on FC5, and the options screen when the app is running allows you to change automute to "off". This does work. I have spent more time on these TV card problems than I've ever spent on soundcard problems on FC1, Debian, Slackware, and Gentoo combined. The last thing I'd like to find out about is what I presume is refresh on FC1, and FC3. On FC5, Kubuntu, and Debian Sarge there are no problems with the images. On FC1, and FC3 I have problems. I don't know the right word, but when images move I get sparkly lines left behind before the image stops moving. Close ups are worse than long shots. Any hint as to what this is, and how to fix it? I may have to start a different thread for this perhaps. Thanks again Peter for the link to the HOWTO. At least I've got FC2 up and running with the TV card. Nigel.
