I appear to have found the previous problem. For some reason Xine 1.0 installed itself in the wrong place when I upgraded.
Reinstalled several things and now the MCOP issue is fixed.
However, it now plays only the audio for MOV and MPG video files. No video and no video window opens.
When run from a Konsole, there is no error message.
I also note that GXine works correctly -- I get video and audio for QuickTime film clips. So, this must be a KDE problem.
