I am planning to buy a PHILIPS 42 PF9630 Ambilight plasma TV. Everyone says you must avoid static pictures or vertical black bars from 4:3 video in a 16:9 plasma to prevent BURN IN. But, what happens with black bars that appear in many “ultra wide” 16:9 DVDs? Do they burn onto de display? Or this model “recognize” this type of black bars? Thanks.
