IDVD Problem with burning a DVD

Question

Whenever I try to burn a DVD using iDVD, I get this message "Multiplexer Error:  There was an error during building.  This disc is still untouched and may be reused later."  I've tried this with 3 different DVDs and keep getting this problem.  Can someone help? Thanks!

Here you go:
1) Delete all old iDVD projects that you couldn't burn under the same name;
2) Reboot your PC;
3) Quit all open applications (check if any is open at "Force Quit");
4) Go to: Users/Library/Caches and delete folder com.apple.idvd
5) Go to: Users/Library/Preference and delete file com.apple.idvd.lists
6) Insert a blank DVD;
7) Go to "Applications" and open iDVD (don't open it from any previous iDVD project);
8) Select " Create new project" and prepare your project;
9) Go to iDVD Preferences / Advance / Burning Speed: and select 4x ;
10) Go to menu "Advance" and deselect "Encode in Background";
11)  At the same above menu, click "Delete encoded projects" and select OK (ignore alert messages);
12) Select "Burn" and... no more problems
