maverick won't play videos

[Brian Wootton]

Has anybody out there got any pointers, none of the media players will play
my videos in Maverick - did in Lucid OK.
  I've added the medibuntu repository, I've added all the codec libraries I
can find, but.......
  All the media players complain in a similar way - below is the output 
with dragon player:
----------------------------------------

"aspect_ratio_menu" with KXMLGUIFactory!

such file or directory
QFileSystemWatcher: failed to add paths: /home/brian/.config/ibus/bus
Bus::open: Can not get ibus-daemon's address.
IBusInputContext::createInputContext: no connection to ibus-daemon

-------------------------------------------------------

what starts the 'ibus-daemon', what is this daemon doing? what would happen
if I invented .config/ibus/bus?
