Jarod Wilson Has used this card and his site talks about what he had to do to use it, although currently his site isnt responding from my location so using google cache, I copied and pasted the relevant section typically found at http://wilsonet.com/mythtv/fcmyth.php here is the cache link I used to find this if I missed any important info, if the link wont work, try searching google for the page listed above and click on "search googles cache for this page" http://72.14.207.104/search?q=cache:0XW7MVoaWtsJ:wilsonet.com/mythtv/fcmyth.php+&hl=en&lr=&strip=1 As for users of the M179 (and probably Yuan MPG600), tuner detection (and possibly msp detection) doesn't work on these cards just yet, so you may have to manually specify them, like so: # ivtv modules setup alias char-major-81 videodev alias char-major-81-0 ivtv alias tveeprom tveeprom-ivtv options ivtv tuner=2 options msp3400 once=0 simpler=1 simple=0 Users of the PVR-350 will need an additional line if they want to enable TV-Out, so their modprobe.conf additions should look like this: # ivtv modules setup alias char-major-81 videodev alias char-major-81-0 ivtv alias tveeprom tveeprom-ivtv install ivtv /sbin/modprobe --ignore-install ivtv; /sbin/modprobe ivtv-fb NOTE: Most of the PVR-350 TV-Out information contained here is derived from the TvOutHowto on the ivtv wiki site, with slight modifications to be Fedora/Red Hat specific (and subsequent changes for 2.6 kernels). We're going to make little modification to the kernel boot line in your grub.conf file that should force the ivtv frame buffer to load on /dev/fb1, as well as allow the ivtv-fb module to be loaded and unloaded. Without doing this, unloading the ivtv-fb module would probably crash your system. To the end of all 'kernel /vmlinuz...' lines in /boot/grub/grub.conf, append 'vga=791', then reboot your system. This tells the kernel to load a frame buffer for your video card at 1024x768, 16-bit color. I use this all the time myself, simply so I can see more when I'm not in X. I'd always done this on my 350-equipped box without even thinking about it, which could explain some of why I've not run into some of the problems other folks have... Now try loading up the ivtv driver: # /sbin/depmod -a # /sbin/modprobe ivtv If you run into problems along the lines of a message saying memory can't be allocated when trying to either modprobe ivtv or use the card (like cat'ing video from /dev/video0), many folks seem to need to use the following command: echo 16384 > /proc/sys/vm/min_free_kbytes Not sure why this is necessary for some folks and not for others (I don't seem to need it). But if that helps, make it permanent with an entry in /etc/sysctl.conf: # echo "# Fix ivtv memory allocation problems" >> /etc/sysctl.conf # echo "vm.min_free_kbytes=16384" >> /etc/sysctl.conf _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
