I am asking Corel about that -- in my own Get More downloads to date, I don't recall getting those ones you listed, and also recall thinking about when they might become available... Will let you know...
Corel has posted these download links in their Knowledgebase as Answer id: 764397 Extra Templates and Title Pack for VSX3. They include Title-01 through Title-06, Style-01 through Style-07, and Incentive. Not listed but available from the same directory are Audio-01, Filter-01, and Transition-01.
Are any others available for manual download and installation?
How do you get the extra content that are not listed on the knowledge base transition-01, audio-01and filter-01?
I tried to copy and paste the link http:/www.corel.com/akdlm/6763/downloads/VideoStudio/Pro_X3/content/GetMore_Transition_01.exe without succes.
This should also give you links for downloading additional content for X3.

Got the 'unlisted' GetMore files the same way you tried -- used one of the listed download files and copy, paste, edit name portion, and click on it. Tried it again a few minutes ago and successfully downloaded Audio_01 (saved as 'copy 2'). [Firefox and WinXP pro]
Don't know why it didn't work for you; perhaps the link has an error that is hard to see -- i.e. is there a space in the middle of '.corel.' ? Try again is the best I can suggest.
