It "burns" to your computer?
Are you clicking "Save to my computer" or "Save to CD" or "Save to DVD"?
If you are clicking "Save to my computer" then answer these questions:
1) What types of clips (extensions for audio/video/still images) are in your
project?
2) How many clips (audio/video/still images) are in the project?
3) Is your hard drive formatted FAT32 or NTFS?
If you are NOT clicking "Save to my computer" then try saving to your
computer to see if that works. If it does there you go but if it doesn't
then please answer the questions above.
