How you are Applying the changes? Because when you click apply in vlite, it ask you how you want to rebuild it. Are you rebuilding a whole thing DVD or just the particular version. I found that rebuilding only particular version and adding languages to it causes some problem like yours. I don't know why...but When i rebuild the entire DVD it worked for me. Note that I don't have the same version as you. Instead I have the Official Vista Ultimate SP1 with English and Russian.
