Have you guys ever tested convert those p8 to p7 MEL?
It seems only FEL compatible disc players are affected.
Would it be possible these deivices never expect P8 DV and their DV engine always assume there is an EL and treat them like P7?
That is strange, proper developed internal player should always have more accurate image than external.
Those engineers who built the TV have a much better grasp of the TV specs, therefore should be able to fine tune it.
