Actually, you take the files that are to go on the cd or dvd and zip them up (winzip.com).  If you have a DVD that's over 1GB, it's best to send that dvd to us so don't worry about zipping those files up.

Once you have that zip file, you upload that to your web server.  You also do the same for the graphic that's to be printed on the disc and any other printed graphics (such as dvd amaray case inserts or jewel case inserts).

From within your cd/dvd project, you then specify the download url to your files (such as www.mycompany.com/files/cd1.zip).  We are then able to download those files to make the disc.  This also gives you control over what files we are using.
