I have written a channel splitter available on my yuvtools
page http://silicon
trip.net/~mark/lavtools/ 
  called yuvdiag.

It's a bit of a hack job, but it shows the U and V channels
in the  
luma channel.  You might find this useful to do noise
diagnostics.
It also has a rudimentary chroma and luma scopes, which I
would like  
to add axis information to.

I wouldn't mind adding more diagnostic features, if anyone
has any  
suggestions.

Sure I'll take a look at it! I'm writing an italian wikibook
about linux 
and multimedia, and I need practice on many subjects to
understand 
important details. Such sort of tool may be of great help,
beyond the 
subject of this thread.

Best regards.
