If you just want to create a data disc with the quicktime movie on it do the following:
1. Insert a blank CD or DVD disc into the optical drive of your computer.
2. Type a name for the disc in the dialog that appears (if CDs & DVDs preferences are set to “Ask what to do”), or under the CD icon if no dialog appears.
3. If you see the dialog, you can choose an action from the pop-up menu and select “Make this action the default” if you want the same thing to happen every time you insert a blank disc. Then click OK.
4. Drag files and folders to the open disc window and arrange the files exactly as you want them. The names of files, folders, and the disc can’t be changed after the CD is burned.
5. Choose File > Burn Disc.
6. Select the burn speed and click Burn.
This is straight from Mac “Help” under “burning CDs and DVDs from the Finder” – there’s lots of good info in Help so I suggest getting familiar with it. Good luck with your new computer.
