Futurama was originally made at (about) 24 fps (something like 23.997 fps); the PAL dvd's speed was increased to 24 fps then an extra frame was added every 25th frame, a blend of 2 current frames... why some ghosting exists (all this depends on where you look; often the cgi was used at 24 fps just sped up to 25 instead of blending). But this means they had to make the audio match; long story short the pitch is slightly higher (the difference is about 4-5%)
Wrong, wrong, wrong. Futurama was made at about 30 fps (actually 29.97 fps) which is the TV framerate in the states. 24 fps is the international cinema framerate, used everywhere. When movies are played on TV in europe, they are sped up by 4%, in america they mix progressive and interlaced frames. The futurama episodes was converted the same way. The episodes on the DVDs are NOT sped up, they added interlaced frames to do the 30 fps -> 25 fps conversion. The "speed up" problems come when you use a cheap DVD player or a PAL->NTSC converter. Again, there's NOTHING wrong with the DVDs!
The best ways to convert the framerates:
Movie -> NTSC : Interlacing
Movie -> PAL : 4% Speed up
NTSC -> PAL : Interlacing
PAL -> NTSC : Interlacing
Some cheap DVD players/converters may speed up instead of interlace.
It is possible to do the 4% speed up without making the audio "pitch shift", and I am shure they do that in Europe. I even found a program on the internet that can speed up or slow down audio files without shifting the pitch.
To avoid framerate conversion problems, people in the NTSC world should use a computer to play the Futurama DVDs.
