The PAL DVDs play the audio about +4% too fast so everybody sounds ever so slightly extra high pitched. PAL DVDs are tricky things when they come from NTSC land. There was probably some deinterlacing done to make them and it could cause them to be even nastier than the NTSC edition. The video segments are inherently interlaced I believe so they would need to be deinterlaced to make a progressive PAL DVD. If there's any weird ghosting in panning shots then they didn't do a good job.
