Rec.601 and Rec.709 are indeed different.  Rec.709 Luma is computed 
differently and the color gammut is a bit larger.  Unfortunately, it 
is not uncommon to see Rec.709 signals feeding Rec.601 displays, or 
vice-versa.

I recommend reading the web sites at http://www.brucelindbloom.com/ 
and http://www.poynton.com/Poynton-color.html.
