    Please forgive my ignorance. There's someone installing a home theatre at the moment. They are going for a Yamaha projector (probably the DPX100 DLP ). they have been told that a cheap non prog scan dvd player (Yamaha 530) will be fine as the projector will do the progressive scan stuff. Is this info correct? I was under the impression that you have to have a progressive scan DVD player. The supplier only does Yamaha stuff and says that there is no point getting the Yamaha prog scan dvd player as this is a PAL player (originally region 2 but multiregion modded).

    Hi

    Yes, that is true. I don't know the Yamaha model in question, but if it has progressive scan built in you are fine just using a standard non-prog DVD player. I've heard that in some cases having both units (the projector and DVD) with built-in progressive scan can be to the detriment of the picture as they can produce conflicts.

    All depends on the quality of the deinterlacer/scaler built into the PJ.

    Some have Farajouda deinterlacers & do an excellent job of deinterlacing - others aren't so good & so really require a prog. scan player for better IQ.

    Don't know the specs of that PJ - try avs for more info.

    If it is the same deinterlacer as the Epson TW100 (considering the LPX500 is a clone of that model with some enhancement tweaks and a redesigned case) then you will be hard pressed to find an external unit that will do a better job with spending BIG monies.

    I tried a Quadscan Pro, Briteview, iScan Pro, iScan Ultra and CS-1 with the TW100 and none of them did as good a job as the internal Faroudja DCDi deinterlacer. I can only presume that is becuase the built in one is optimised for that unit.

    IMO, unless you are prepared to spend meag bucks I wouldn't even bother.

    They certainly don't have a Farajouda deinterlacer - that's for sure. Accordingly they'll never equal the TW100 (& clones - Messiah ;) ), which is without doubt, the best at deinterlacing (on board).

    The AE100 really benefitted from 1:1 mapping via VGA so it's scaler isn't great either. Can't comment on the AE300.

    ALL fixed pixel projectors work progressively. They ALL are therefore are doing progressive scanning. None require a progressive scan source to do progressive scanning.

    As has been stated above the difference is only in where it is done and how good the device doing the de-interlacing is. There is more to video processing than de-interlacing though so there may be reasons why external videoprocessing, in DVD or in a seperate box, may be better than that inside a projector. The best way to check is to do the dem.

    Hope this helps a little.
