Hello :) ,
I've just recently tried downloading all the packages needed by kdenlive as well as kdenlive itself -- I used the instructions on the main page ( http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/... ) to do this (though faac was found at a slightly different location ( http://www.slackware.org.uk/3rd-party/alien/restricted_slackbuilds/ ) . I've installed all the neccecary packages from alien bob's site, but if I try to start kdenlive I get a little window from the config wizard;
Checking MLT engine
* Melt (/usr/bin/melt)
X Avformat module (FFmpeg)
* DV module
* QImage
(the avformat module is missing!)
But according to ffpeg itself I do have (lib)avformat;

Does anyone know what could be producing this problem? Thanks :)

Yep, I used the kdenlive packages from here http://www.kdenlive.org/user-manual/downloading-and-installing-kdenlive/... and the ffmpeg from http://www.slackware.com/~alien .
edit: I tried the 32-bit packages on a 32-bit system (slackware 13 still) on a different older system as well as the 64 bit packages on my main system, same problem x.x
