HQR1 DVR offers two encoding formats, MPEG-2 for DVD and MPEG4 for archive

MPEG-2
MPEG-2 is a standard for generic coding of video and audio. It is widely used in
consumer electronics, such as DVD video disc, DVD player, DVB television
broadcasting etc. The HQR1 DVR can record in MPEG-2 format which can be
edited by any video editing software or replayed on a DVD player.
MPEG-4
MPEG-4 is the awesome new generation video standard with better video quality
and higher compression rate. For exceptional disc space saving, MPEG-4 is
capable of creating highly compressed video archives on a regular CD-ROM with
almost the same quality of DVD. One popular MPEG-4 format is DivX. It is the
only technology that enables streaming of video on the internet possible. Now,
many DVD players can play DivX files directly.
