Does your version of this software support Tiger? I note that they have different versions for different OS's. A defrag of the HD is not considered necessary with OS X as the system will perform that function when a program is installed. It also manages the file allocation much more efficiently than the average PC.
Poking around in the Terminal is fraught with danger unless you know exactly what you are doing. What were you trying to accomplish in there with QuickTime? The word "or something" is particularly worrying.
To change passwords on the machine, booting from the OS CD and using the Password Application is the usual, recommended way.
In the absence of any further advice, from other posters, I would suggest that you re-install the OS using the Archive and Install feature. This will place a new, good, copy of the system on the drive and preserve all your documents and other stuff.
One further piece of advice, stay out of Terminal

Hi, I was wondering if anyone has had any trouble with their iMac G5 keyboards? My existing white bluetooth keyboard won't respond (last night it appeared to work fine and it had almost a full battery level). When I turn the keyboard on, it flashes a yellow/green light. I have tried replacing the batteries and it still won't work.
The second part of my problem is that when I use my Dad's black, wired Apple Pro Keyboard to log in to my username, after I have clicked log-on the system locks up with a lollypop/beachball symbol.
I have defragmented my computer using Drive Genius and also checked for bad blocks, as well as repairing/rebuilding my hard disk. I also repaired Disk Permissions for my hard disk.
Last night, I installed Limewire and downloaded a few files. I also went to the Terminal to edit (Applications/Quicktime/Contents/Mac OS/Quicktime)or something and I changed some values. This might have contributed to my problem. I also used Netinfo (Applications/Utilities/Netinfo-I think that's what it's called) to change the root users password. I changed it to 1 I think and saved the settings. I also changed the log-in screen to show username and password fields instead of just the pictures.
I am sorry that this is such a long post, but I thought I should go in to depth about this problem, can anyone help me? I really don't want to install Mac OS 10.4 AGAIN!?
