MPEG
Moving Picture Experts Group ( .Mpg or .Mpeg ) built as a standard for compression results digital video - audio files. This format produces high image quality, but not require large file capacity.

While the MPEG - 4 format , with a capacity small, supporting transmission network via air-small bandwidth. Generally, the video camera Digital was able to generate output MPEG.
DivX
DivX, commonly known as "video MP3", developed by DivXNetworks. the format is file-based video compression MPEG-4.

MPEGAV folder. usually titled AVSEQ.DAT. Files . Dat is compressed AVI file into MPEG, VCD and adjusted in the structure. To make it you can use diverse applications burner.
