I just played around a bit with kdenlive-0.7 and stumbeld on a problem with XVid4 rendering. When I choose XVid4 in the rendering dialog, I cannot choose a quality- as switching to something different that 200k doesn't change anything in the command that is passed by the programm (which can be seen when the "Info"-Button is clicked). Which other codes than XVid4 it seems to work!
Also there is no progressbar for rendering, or?
I'm running kdenlive on gentoo, builded from source.
