never was.  nuvexport reencodes, it's not lossless unless you use the 
mpeg2cut function..  and even then, mpeg2cut calls avidemux, which can 
reencode frames around the ones you cut out, without cutting at a GOP 
boundary..  and the reason why the semi-obscure lvemux was used for 
remultiplexing is that it can handle putting things back together in a 
way so as not to get av sync issues.

I believe that myth puts them in if you leave them out.

Pretty sure this is an artifact of a VBR encoding.
