3ivx and QuickTime?

I have a few DivX movies, and I downloaded the 3ivx D4 PR1 Decoder for OS X, and 3ivx Doctor II. I read the instructions for installation in OS X for the 3ivx D4 PR1 Decoder, in which it says for OS X, you must put the decoder in the QuickTime folder, which is in the Library folder, at the root of your system.

So, I tried to do so, but I get an error telling me that the QuickTime folder cannot be modified.

Now, I am the first and only user on this computer, so what is the problem?
Has anyone encountered this before?

Arn...

What do you mean by copy and paste the QuickTime folder line here? What is the quicktime folder line? Could you guide me through this real quick?

My line says...

This is what my line says...

drwxr-xr-x 7 root admin 264 Apr 20 12:34 QuickTime

Arn...

So, when I open up Terminal, I type....

sudo chown jcarian /Library/QuickTime

Is that right?

Or is it...

sudo chown <jcarian> /Library/QuickTime

Do I do this without doing anything else? I dont type that ls -l /Library/ stuff?

yay!

I got it! I have no friggin clue what I did. I THINK I typed in ls -l /Library/ and then type the sudo crap. Thanks alot arn!

Hehe...

Thanks again man!

One last problem

I grabbed my .avi (Lord of the Rings) and dropped it into the DivX Doctor II program. I have installed the 3ivx Delta 4 PR1 program.

When I select my .avi, and select "start," it converts it all the way to the end, but it stops and says "waiting for Quicktime to flatten (avi name)"

It wont do the flattening! What do I do?

Ahhh....

I see now. I must be pacient, young gwasshopper.

Thanks again arn!
