mpeg2 from VOB (DVD-Video) to try to convert

Description:
Recently, DVD Album wrote an article about. DVD Album format is handled, mpeg (DVD-Video formats are limited) could only.
It can not treat General mpeg2 files. Therefore, mepg2 the file if one tries to edit the DVD, once, I have to convert.
In the first article of the mpeg (DVD-Video formats are limited) is that, in general, VOB are known as the format, video format is stored in mpeg2 format.

So, VOB's, mpeg2 you something different.

The VOB, mpeg2 is a wide range of acceptable speech, additional information (information such as subtitles and audio split) and DVD-Video includes such information as may be declared. VOB, once in Japan, LPCM (linear PCM) or AC-3 (AC3) and given the circumstances, MP2 (most mpeg2 audio format) was also unable to play. (In recent years, mostly in consumer electronics that can play the story MP2 Listen)

So, to convert the popular use Any Video Converter, It can convert and then you can certainly convert.
The set of parameters (most of the bit rate) by changing the file size.
By each tool, encode (format conversion), so I think a different way, is not nothing, that the file size is different, the original information, but is set to note that it is not you need.

Such a conversion tool to respond to various file formats, how to convert, the conversion to a common internal format, you also have to convert.
Therefore, what happens to the file size changes. (I imagine. It may therefore take longer to convert. )

Now, as mentioned earlier, mpeg2 video, is supposed to be good at it, because there are some differences in format, but not exactly the same size, roughly, is the same size should be able to convert .
So this, mpeg2 from VOB (DVD-Video) to convert to the file size is almost the same about how I would like to write.
