Are you transcoding to MPEG-4?  If so, what is your bitrate, also, what 
do you get when you inspect the final .nuv file using tcprobe?  It is 
quite possible that transcode *did* succeed, it just happens to have 
created a file with approximately the same output size.  I've had that 
issue with some files.  The bitrate controls the final file size.
