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."
Just because it is in a magazine doesn't make it right. If you rename a
.nuv file to .mpg, it will play in most video players, from my experience.
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?
Because the bitrate is different, perhaps? The .nuv file IS MPEG2,
despite what you want to believe.
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?
Depends on the driver for this imaginary PVR card. I don't know of any
that will record to DivX directly.
