AND
is there a quality or size different between two .mpeg-2 and .vob file(bothe in 9.5 mbps and 720*572

isobuster can get the mpg from a dat file.

dat is a storage container file type as is vob. MPEG 1 is the video format for vcd and mpeg 2 is the video format for dvd.

15000 mbp is above the dvd standard.

This will give you the basic specs:

Again vob is the container for mpeg2 files to make a dvd.

thx but i mean when i buy a vcd from outside the quality is really good but when i try to capture mpeg-1 the quality becomes bad.why?
and can i burn XVID on dvd or vcd like mpeg?

Professional dvds would use a higher quality source.

You can burn a xvid as a plain data file but you will need a divx compatible dvd player to read it. Otherwise you will have to convert the xvid to mpeg2 and author a dvd.

VCD's are generally down-converted from DVD's thus they have good quality visually, at least on regular TV.

See the tools section for AVI -> VCD/DVD converters (it's skipping a few steps, but there are tools that do that)
