I loved my last iMac. This one is a major pain in the ***! Doesn't open Quick time files from friends. Doesn't categorize documents into folders. I am so bleeping unhappy with it I could almost go back to a PC..
So what OS version are you on? Your profile says 10.4.8?
If you are on Lion, you now have Quicktime Player X (10) installed by default - you can download the older version 7 if you don't have it which may help.
Not sure what you mean with categorizing documents. Can you give a few more details please.
