Ken writes: I foolishly put last Saturday’s Independent’s free give away DVD in my mac despite the warnings against doing just that printed in small type on both the disc and the sleeve it came in. The problem comes from the fact that the DVD is half the standard thickness and doesn’t properly engage the mechanism that returns the disc when you try to eject it. All this week I have been forlornly pressing the eject button in the hope that the mechanism will work more effectively for some reason. All was to no avail, until today. The disc finally came out when I held the laptop on its side in the air with the slot pointing downwards. Perhaps the force of gravity helped.
