Its A Little Blurry So Make It Full Screen The First Time You Watch It.
The Video And The Settings Are For Dreamweaver 8. The Settings Are The Same In All FTP Clients. I Think That You Set It Up The Same Way In Dreamweaver MX But I Do Not Know About Dreamweaver CS3
Also To Upload Click The Arrow Pointing Up Above The Files
If You Can Not Read It The Settings Are:
No, I Do Not Want To Use A Server Technology
Connection: FTP
FTP Host: ftp.yourdomain.com
FTP Password: Set Up In cPanel
FTP Username: Setup In cPanel
FTP Path: Can Be Edited And Viewed In cPanel
Use SFTP: No
Just Go Into cPanel And Click FTP Accounts To Set Them Up.
Also Once You Have Clicked "Manage Sites" In Dreamweaver Use The Basic Setup Not The Advanced. There Are 2 Tabs At The Top Of The Setup Window
