"Gentleman" Codegeek is one of our most amazingly helpful and giving members, something you may not be aware of, given that you are very new. While he could not have known what kind of research you had performed, what he was doing was providing information as a step for those who are inclined to try and dig up a solution for your question. Sometimes we get lucky and get answers to our I.D. questions immediately, other times multiple minds pitch in and it becomes a team effort. He deserves gratitude for taking his valuable time to assist others.
Frequent bumping does not help, and is also frowned upon. I wait months before bumping my own questions, not only because it's the polite thing to do, but also because I'm aware those experts who take the time to read I.D. threads will likely have seen your thread. After the passage of more time, there may be a set of new eyes that will increase the odds of helpful tips or solutions.
I'm familiar with this movie, having written about it here; I also provided a download link which is still working, in case others may be interested (including potential problem-solvers who could use more reference). Member Jerry Fearsome has done wonderful work in compiling I.D.'s of the non-Japanese ladies, but this one has not yet been touched. The ladies are Czech, so maybe that decreases the odds for many who may not be familiar with Eastern European porn performers. If you don't get action here, you could try posting in the Collection of JAV with White Actresses (and a Few Black Ones too)thread. (It's not really an I.D. thread, but if you're friendly, they may also be friendly.) You can also take a shot in other sites that are more into the non-Japanese, such as Freeones or namethatporn, or namethatpornstar.
