Guys, thanks for such a prompt reply!
But I think you miss the point.
Those of you who read the last issue of Linux journal, the "Advanced MythTV Video Processing" article must note, I citate:
"Although digital TV recordings are an MPEG-2 video stream, the NuppelVideo container format used by MythTV is specific to MythTV and is not supported by most video player software. To watch the videos with anything other than a MythTV front end, you must convert them to a format with a wider selection of players."
I need to use mythtranscode tool to convert the MythTV recordings into more widely supported formats, means it's not MPEG-2 format.
Additionally, as I understood, if you take a file in Myth native format with resolution 704x480 which size is 1,756MB after decoding it to DVD (i.e. MPEG-2) format, the file will shrink to 899MB.
Now is the one million dollar question, why the native file (original) is so large?
Another example, what if I have PVR which has DivX encoding capabilities, whould MythTV save it in DivX (as I expect it to be), or in its native format?
Thank you.

If you want proof, try file:
$ file 1018_20050115160000_20050115170000.nuv
1018_20050115160000_20050115170000.nuv: MPEG system stream data
This isn't Windows. File extensions mean nothing.
Some broken operating systems decided to use file extensions as a way of
identifying file types because they couldn't figure out how to do it
right. *nix doesn't suffer from this inherent limitation of those other
OS's.
