While installing Kino, I see that libdv is needed. I checked and it's already installed, so I do a ./configure again in the download folder of Kino and libdv is still not found.
I downloaded libdv from official mandriva sources and un tarred it to my download folder. I repeated the installation as standard and again tried ./configure in the kino folder. Same result, libdv not found. The error message indicated that it's possible to set CFLAFS and LIBS in the pkg-config but now I'm a bit lost. What's the syntax, I've found nothing in the man pages or on the web.

There should be no need for you to compile kino. If you have setup your sources correctly (use the easyURPMI link in my signature if you haven't), you should simply go to commandline (or use the package manager) switch to root then type urpmi kino. The configure script is probably looking for libdv in the wrong place.

I did easy urpmi and it worked well thanks.
I launch kino from konsole and:
kino: symbol lookup error: /usr/lib/libavformat.so.51: undefined symbol: av_opt_set_defaults

Did you select 2007.0 from the sources list on easyURPMI? This error will occur if you have the wrong version for you distro installed. Do this as root at the commandline: urpmi libavformats51 libavutil49 libffmpeg51, that should install the correct version of the libs required.
