Now that the QT portion of your problem is resoslved.......
Apparently, your only problem now is trying to burn a .avi file on a DVD and getting sound?
You will need to repost in the
MacBook Forums where users using the same model computer as yourself will be able to help you.
Another sourse: Click on your desktop>Finder>Help>Mac Help
In the search field type
dvd or
dvd burning. Basically the same help topics come up.
Finder>Go>Utilities>Disk Utility
Click on the "?" in the bottom left corner. The Help window will open up.
Type the same thing as mentioned above. For some reason, there are a few different DVD Help Topics & a couple of Support Articles.
A good reference book for a newbie (I am also a newbie to the CAT System still learning my way around but, not to Macs):
Mac OS X: The Missing Manual, Tiger Ed - David Pogue . This book is very easy reading, non technichal & non geeky. I
strongly recommend this book as it takes you step-by-step through Tiger.
A few others:
OS X For Dummies
Tiger For Dummies
The latter 2 books can have several authors as there are a
series of them. Use Google and/or Spotlight to search:
Authors to look for: David Pogue, Bob LeVitus, Mark L. Chambers, Larry Ullman, Marc Liyanage.
Good luck!
