PREVIEW and QUICKTIME slow to load in SNOW LEOPARD

I've just started having a problem (after years of working perfectly) where files are taking FOREVER (up to 30 seconds anyway) to load in both PREVIEW and QUICKTIME.


This occurs both when opening files fully with double-clicking - and when wanting to Preview by just pressing the space bar. I utilise the latter frequently to audition samples (as I work with music/Logic). This used to be an instantaneous process but can now take up to 30 seconds with the "Loading Preview" message before finally loading.


It seems to be happening with all files, irrespective of size or type (ie mp3/WAV/AIFF/MOV etc)


Very ocasionally - and apparently randomly - a file will load quickly.


I've tried reparing Permissions, running Disk Warrior, reinstalling Preview, uninstalling Perian, opening another User account (in case there was a software conflict of some kind), and cloning my System onto a brand new HD with lots of free space. But none of these have made any difference.


Anyone have any other ideas as to what this might be?


Cheers in advance:)

Mac Pro, Mac OS X (10.6.8)

hey andy


yeah there definitely appears to be some kind of issue (with core audio?) when i check out Console as this happens.


i've looked at the subsequent diagnostic report but not sure how to interprete it.


wold it be useful to post it here?


cheers

I narrowed it down to my MOTU audio interface causing the crashes. In fact it was crashing Core Audio intermittently whenever it was connected (ie all the time) - and turning it off has sped up many other processes (eg internet browsing) that I would never have considered related.


Your help, particularly pointing me to Console, has led me to the culprit. Much appreciated:)
