Although I'm a n00b to this game I think I understand the basics and know what PS is ... I think. While browsing the A-V Sales special offer page I came across a Zinwell unit. I've just tipped my toes in the water by buying an AE300 which I'm in the process of installing .. with that in mind ... AIUI, if an interlaced signal is fed into the projector the pj itself de-interlaces it, but a source such as a DVD player can output in progressive mode in which the case pj simply processes it as-is ... if I understand things right, the choice is down to the relative quality of the de-interlacer in the player and the projector. Clearly external de-interlacers/line-doublers like the Brite-View are another option. My question is this: given I have an AE300, how do I determine whether to go for a DVD player with built-in PS mode or a lesser player but an external de-interlacer .. or whether the AE300 isn't good enough to show any difference from its' own internal components. I hope this isn't a meaningless question.
