As far as I know .nuv is (just) a container format like .avi.
RJPG is the video codec/format that is used to compress/encode the video 
information inside this audio+video-container-nuv-file.

So I thought the missing information could be missing in the .nuv part 
of the file or the RJPG part of the file... but maybe I am talking blue 
here, because I am missing some video-format knowledge here... :-)

But is more likely that the information is missing in the RJPG part, 
because...
there is also the possibility to create .nuv files with DIVX inside with 
mythtv. And these files can be played with mplayer!
I appended file informations about such a file.

I am trying to get some more information "from the other side".
Unfortunatly until now I only heard that there is just the source code 
of mythtv as specification :-(
But I will try further!

You got this wrong. I wanted to express that "I can't expect anything 
here", because it is not /your/ task to puzzle the format of mythtv, but 
should be mythtv's task to provide you with the according information.
I really did /not/ want to express in any way that I don't expect help 
here or something. The opposite impression is the caase: I really find 
you very helpfull / willing to help!

Greetings,

tormen.

P.S.: How can I get completly "english" output from mplayer?
I tried to set all locales to POSIX... but still german.
