I would like to know if the episodes are complete or edited. This set has running time listed as 2358 minutes, while the US set has a time of 2580 minutes. The US set does have some extras, but I don't know if they are included in the time. Also, I doubt the extras would be 228 minutes. I hope someone who owns this set can help me. Thanks in advance !
It's just PAL speed-up, as the other guy said. Compare any PAL Vs NTSC DVD sets and you will find the same discrepancy in running time. It is not the case with Blu-ray, but VHS and DVD were both affected by this. So yes...it is very much complete.
Do you want to know an interesting fact regarding this issue? Some people's hearing is so well attuned that some Americans watching a show they are familiar with on British TV for the first time can actually hear the higher pitch in the actors voices owing to PAL speed-up. However, most people are not aware of it. I was watching an interview with a Star Trek actor once and after the presenter played a clip, he asked why the actors had "squeaky voices". Yet it sounded perfectly normal to everyone else. That is PAL speed-up.
