I read in a review that Sony's DVP-SR200P DVD player is just a re-branded Philips machine. My question is whether all of Sony's DVD players are re-branded from Philips, including Sony's DVP-NS710H and DVP-SR500H. Philips has some products labeled "DVP" itself. Does anyone know if this is the case, specifically with the latter two machines? Why would a company re-brand another's machine?

Also, does anyone own either the DVP-NS710H or -SR500H and can give a review of their quality? Thanks!
