Quoted Original von anda_skoa KWallet. But I don't know if Konqueror will use to store input from password forms. Yes, it does. Optionally, of course. KWallet fills in forms, but does not submit them (in order to give you a chance to edit the entries in case you're doing something different) Also, some sites take special pains to make it difficult to autofill passwords, there's not much to be done about those.
kmplayer is in kdeextragear and therefore developed along with the rest of KDE now. Noatun and kaboodle both can use xinelib to play movies (success of this might depend on your distribution and OS however.) Kaboodle is small, a single shot player that works nicely from the commandline, and embeddable, it's not just taking up space.
Run kcontrol, look in the 'accessibility' -> 'keyboard shortcuts' section. Part of this applies to KWin, but the ones you want are in the 'application shortcuts' sections. You might want to check the alternate schemes, one of them might already suit you.
You can see the list of installed kioslaves in kinfocenter in the 'Protocols' tab. kmd is not part of the default KDE installation, but it might be installed automatically by your distribution's packages.
mplayer can play a lot of Quicktime content, if you have a recent version.
First, read the excellent FreeBSD handbook, and learn how to cvsup your ports. Next pick one of: cd /usr/ports/net/psi && make install clean or pkg_add -r psi or portinstall psi or portupgrade -N psi The first will build it locally, the next will fetch a package, the other two are aliases to the same command but will build the port locally while keeping your package registration database nice and clean. If you want to use portinstall/portupgrade with packages, but falling back to the building it...
I think you misunderstand what the mimetypes do. If you go into KControl and associate audio/x-scpls with Noatun, and then find a playlist file and doubleclick on it, Noatun should open that playlist. The filter box at the bottom of the open file dialog is simply list of default things to look for, not a comprehensive list of all the filetypes an app can possibly handle. It's editable though, so just type * or use the dropdown box to change to that, and select your playlist.
