Did you look here:

http://www.mythtv.org/docs/mythtv-HOWTO-21.html#ss21.1

Myth's .nuv files are a special tweak of the NuppelVideo format by 
Isaac.  They are /not/ standard NuppelVideo files. (Unless you're 
recording with a PVR-x50, in which case the files are really standard 
MPEG-2 ".mpg" files with the extension changed to ".nuv").  See the 
above link for some tools that can help you transcode to a standard 
format.
