Auto Format on Philips 42PF9965 Plasma

Having previously connected the following 2 DVD players ( Pacific , Wharfedale ) to the plasma the Auto Format filled the 42" screen regardless of which DVD was being played. Recently I've purchased a Philips DVP630 Divx payer with progressive scan and when certain DVD's ( Stars Wars, LOTR, Indiana Jones ) are played the Auto Format does not kickin, and there are black bars top and bottom of the screen.

I'm interested to know if anyone else has had the same experience with the auto format on the Philips 42PF9965.

Anyone any ideas ????

 

DVDs recorded in 2.35:1 cinemascope are meant to have black bars above and below the picture (the screen aspect is only 1.78:1 widescreen). It is likely that the 2 DVD players before were erroneous and the DIVx player is actually getting it right!
