I tried to use the NTSC DVD as "patch" to cover the TV logo, with various results... from almost perfect
before
after
to pretty bad...
before
after
this is because cropping of the DVD varies throughout the film, and the color grading isn't perfect in all the occasions... with a lot of work, result could be "bearable" and still better IMHO than a piece of logo so evident like this, but I wonder if there is a web rip somewhere, or even another HDTV version (720p will do) without the "Canal+ HD Accion" logo... Can anyone help?
