That's Cheap!! I know getting the subtitles to be in correct placement with each frame and having the words remain there long enough for each spoken part takes lots of time. Wouldn't be worth the time and effort put in to charge that much. I hope you placed encryption (macrovision or CSS) to keep some of those from bootlegging your hard work.
Having had the great pleasure to see Andy's work with his Charlie Chan set of DVDs, I am willing to wager ($14 on "Schnozolola") that he has done his usual professional job with this "ERAN TRECE" project. Whether or not any steps have been taken to prevent others from making copies, I do not know. However, if bootleg(!) copies begin to appear, at least we can rest happily in the fact that there is a great interest in Charlie Chan's adventures, including "ERAN TRECE."
