I just got my copy yesterday and noticed a slight problem with at least the first episode. In season three the shows theme song was re-recorded so it sounds slightly different then the version used for seasons one and two. Now the problem lies in the fact that in episode one the old theme is used and it sounds muffled. I quickly checked another episode on the disc and it was fine but have not had time to check the others. Now what is getting me ticked off is that the region 2 version has the correct theme so this was deliberately changed for the US release and i'd like to know why. I'm hope someone could shed some light on this and report on any additional problems that may turn up.
