One person on the official site's forum received a replacement disc which fixed the skipping errors, and confirmed that none of the other defects I noted were corrected. He said something to the effect of "For now, we'll just have to live with it. We shouldn't have to, but we will."
I reply: Why should we have to live with it? You paid good, hard-earned money for a product that should be correct. If they were willing to fix the pressing errors, why not the mastering errors? If you bought a brand-new car and the rear speakers were wired in reverse, would you not take it back in to be fixed? Or if the fabric on one of your seats didn't quite match the rest of the interior? Or if the timing were just a little off at startup? All three of these are analogous to the defects in the Star Wars disc. Now, if every car rolled off the assembly line with these problems, there would be a massive recall announced to correct the problems. If consumers do not stand up for themselves, businesses will only take advantage of them. Why should you just accept a defective product?
I emplore you all to start a letter writing campaign to correct the defects we're pointing out in this thread. The BBB will pay attention and will definitely take strong action, even if just a few dozen letters come in on the same subject. Even Rome was built brick by brick. Take action against Lucasfilm and they will be forced to correct their errors.
Updated
On a positive note, I DID speak with somebody at Fox's disc exchange program this afternoon for almost half an hour. She is going to personally try to get better answers on the issue. I still think that Lucasfilm was in such a defensive posture over the OT/SE debate, that their knee-jerk response on the audio problem was to defend it as another creative change. But I digress ... Having a person take the time to actually hear out my issue thoroughly, be sure she understood the issue, clearly get the fact that these changes were different from the "bad production run" that they are fixing, and then take my name and number and promise to get back to me after really tracking down the issue, well, this is promising. Now more than ever, the volume of complaints will underscore the widespread nature of the problem.
Update 2
On a second postive note, I just got called BACK from Fox, apparently by the boss of the person with whom I spoke earlier. He spoke to me for another 10-15 minutes wanting to be sure that he understood all of the issues (and I'm confident he did). He seems to want to get to the bottom of this. While its ultimately a Lucasfilm issue (and he seemed to indicate that Lucasfilm is going to ultimately do whatever they are going to do) he did seem poised to discuss the issue with LFL intelligently. Having an insider talk with Lucasfilm has more potential than just having an angry fan bitching, but that said, I think a hundred angry fans bitching all at once in the right direction will also have an effect.
