That 8-centimetre-wide dent in the tray of your DVD player is now explained. It鈥檚 designed to play small recordable discs from a new type of camcorder, the first of which will be launched by Hitachi this month. The DVD camcorders compress pictures and sound to the MPEG-2 standard, storing up to an hour of footage on the mini DVD. Users won鈥檛 need to invest in expensive FireWire cards for their PC either, because the new disc-cam records video at a much slower rate than Digital Video (DV) camcorders. This means users can transfer video to a PC鈥攁nd vice versa鈥攗sing a standard USB connection, at two or three times normal play speed.
