Deinterlacing in Kaffeine can be switched on and off by pressing i and
the deinterlacing quality can be configured by pressing ctrl-i, but this
doesn't have any effect for me.  DVDs are always deinterlaced and xvid
movies never, regardless of my settings.

Use mplayer instead of kaffeine :-)

"mplayer -vf pp=li <file>" deinterlaces the video and "mplayer -vf pp=li
-aspect 4/3 <file>" additionally changes the aspect ratio.

But I also think it would be better to have a deinterlaced and aspect
ratio corrected xvid videos because of less trouble with different
players :-)

But why does deinterlacing highly increase encoding time while mplayer
can deinterlace in realtime with even better results?
