I FINALLY sorted this out!

Irritatingly, MovieShaker will only provide sound with the version of Quick Time that was supplied on the CD-Rom. If Quick Time has been upgraded (this can happen automatically if you agree to future upgrades) then it ceases to work properly.

To resolve the problem:

* Uninstall the MovieShaker software
* Uninstall QuickTime and any QuickTime plug-ins/components
* Uninstall Direct X
* Restart your computer
* Install the copy of QuickTime from the MovieShaker CD
* Install DirectX
* Install MovieShaker
* Restart your computer

Bingo!

The pain is that your iTunes will not work. Personally, I use the latest Quicktime and I have resigned myself to having to go through the above procedure each time I want to download my video.

Hope this helps - isn't the internet great - it might even catch on!!
