Though it should be noted not all PAL DVDs have sped up audio. I have a few that were straight NTSC conversions w/ frame blending interlaced video. I even have a few newer ones (they are Japanese Anime PAL releases) that are progressive 25fps using some type of frame blending as they run identical to the NTSC versions. Neither of those are running any faster. Some PAL movies are sped up but the pitch is preserved so playing it back at 24 would result in a lower pitch.
