is that Apple has recently changed its tune regarding VM. Previously
they said that VM should be off for smooth DVD playback but now they
say it needs to be on. Indeed DVD playback is crap with VM off.
But there's a workaround for this and any other time you need to enable
VM when 1GB of RAM is installed... Just create a small RAM disk of
approx 40Mb and this will fool the Os into allowing you to turn VM on.
