I confirm this problem, it affects DVB as well as DivX videos. However, I think it is not a problem of kaffeine as it affects mplayer too. Video playback with "auto" video driver with xine-ui and "gl" driver in mplayer gives a kind of interlaced image where each scan line is "moved" with respect to the previous one. CPU usage goes to 100% during playback.
I think the cause is the fglrx driver as the playback works fine with radeon driver. Video playback was working fine with fglrx in edgy. When running kaffeine from command line, the following two lines appear (among others): Xlib: extension "XFree86-DRI" missing on display ":0.0". video_out_opengl: compiled for BGRA output, but missing extension. -- [feisty] video playback does not work with kaffeine https://launchpad.net/bugs/92816 -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
