[mythtv-users] NuppelVideo container format

[Felix Rubinstein]

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.
