Fixing PAL speedup and how film and video work

I have a large collection of DVDs and I live in Australia. Because of history this means most of them are in ‘PAL’ format. This means they tend to be about 4% faster than they should be, resulting shorter playing times and higher pitched voices and music.

I’m a bit of a purist. This bothers me enough that I must fix it! What follows is a somewhat lengthy explanation of how film/video works, followed by instructions on how to use my fix-pal-speedup script.
