Samsung is making a major push on several fronts, including DVD, hard disk, and flat screen technologies. One of the more intriguing prototypes on display at the LV Convention Center is the company's DVD player/hard-disk recorder combo, whose 50GB drive can accommodate up to 20 movies. The films can be saved in a compressed video format directly off DVD and watched as often as you like. There is no digital output on the machine (it does have analog component video out) so there is no easy way to make digital copies. Like TiVo's PVR, the Samsung recorder will require deleting some recordings when the disk is full. The fact that the recordings are not transportable helps Samsung skirt copyright issues, according to a representative.
