Apr 27 01:44:37 hacky.local iTunes[402]: AVF error: fail to create QT accelerator
29/04/13 8:17:30.442 AM CVMServer[114]: Check-in to the service com.apple.cvmsCompAgent_x86_64 failed. This is likely because you have either unloaded the job or the MachService has the ResetAtClose attribute specified in the launchd.plist. If present, this attribute should be removed.
Additional notes. I received this error upon closing iTunes after attempting to play video.

Can you guys open the console. Hit the 'Clear Display' button, run iTunes and attempt to play a video. Then close iTunes and see if you get any new input in the console. If so, add below.
