Micro Pocket DVR can record in MPEG-2 format which can be edited by any video editing
software or replayed by DVD player.

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

streaming of video on the internet possible. Now, many DVD players can play DivX files
