Hi, here is one of the answerbase search result. Error -6045: DSP code was too slow to keep up - could be caused by video capture cards on the same bus. Try moving other PCI cards (video,SCSI) or using fewer tracks. - This error can also come up if the "ATI Driver Update" extension is installed. Try removing it and rebooting the Mac. - Try increasing DAE playback buffer size to 4 or 8.
