    Your dvd is set to output NTSC as pal, a feature for UK tv's

    Excuse my Ignorance but,

    Is this how it should be setup (my Tosh SD530E only gives an option for Progressive - it doesn't differentiate between PAL & NTSC)

    Consequently, given that the 433MXE will accept NTSC PS, will the PQ be suffering when playing NTSC discs or am I better off with 625p for both formats? :confused:

    cheers

    Ignorance? it's pretty complicated, When your dvd outputs NTSC as pal, it is scaling the picture from 480 to 576 lines. This is then scaled by the display to 768. You are right, it's better to scale once, and it's likely, well hopeful really, that your 3.5k display scales better than a £200 DVD player. In fact the same goes for progressive scan. You have to do all the processing somewhere, best to do it in the highest quality place. Try it both ways and see if there is a difference, and do it the way you prefer.

    Hello both

    Pedromartinez - is there not an option to switch off the 'display NTSC as PAL' mode in your player; or are you saying that's a feature of the Progressive mode!

    Best regards

    Joe

    PS MAW - got a note on Friday from Pioneer UK - NO MORE PDP-503MXE in Charcoal (still a few Silver left though).

    I am a bit confused by all this myself, would a Denon A-11 or Denon 2900 show similar results to a Iscan Ultra HD or Ultra if i connect it to this plasma? or would the Iscan show better results?

    The Ultra is no good to you because it only outputs 480p or 576p, neither of which match your display. You should be better off with the Denons, since they have good I-P conversion and will do it in the digital domain. I believe the Ultra HD is your best bet since it will output at your panels native resolution, and presumably better than your PDP.

    It's a bit extreme to saay the ultra is no good, it has very high quality deinterlacing, and will do quite a lot for PQ in spite of 'not being a scaler'. But the HD outputs 720p which still leaves a discrepancy? I have not yet seen a manual so maybe you can set it to xga?

    Joe,

    My DVD Player is a Tosh SD-530e. Within its setup you only have an option to turn on/off progressive scan. It does not offer you any NTSC/PAL options!

    Given that on my 433MXE, both formats appear as 625p, does this mean the player is outputting NTSC as PAL PS? ( and consequently, will the PQ therefore be degraded? )

    cheers

    It must be as the screen is recieving a 625p signal. There will be a small picture quality loss, but not massive. 2 stage scaling is not the best idea, you have to ask yourself if it's worth upgrading the dvd player though.

    No you misunterkushtuble, which isn't suprising when I read back my own post
    Lizzard asked about the Ultra vis-a-vis the Denon A-11/2900, in which case I don't think he would see a worthwhile improvement. Since his PDP is HD then he needs high quality scaling, which the Ultra won't provide, therefore I meant the Ultra is no good to him. I know it's a cracker I have one!:smashin:

    Have you set the little switch on the back of the player to auto, or is it set to pal.(if it has a little switch that is, but most do)

    Just an off the wall thought here, but if you are looking to revise your system and you already have a MXE, have you considered the HCPC route? Go for a 3803 instead of the A11, and build a quiet pc with nebula freeview card instead of the 2900, spend the change on filling the fridge with beer, and enjoy spectacular pictures with DVD and tv via DVI, whether PAL or NTSC.

    Yes, maybe with a Panny you might, it's when you get to hi res it starts to make a difference in my experience. Also, if you are using DVI to a PW5 the problem is cos the dvi board for 5 series is xga only which doesn't match the screen res. Your screen is still scaling, use VGA instead.

    No i was refering to the projector, use the tosh with the pany.

    I think its more to do with the de-interlacing job, as the faroudja chipset helps with image artifacts like edge enhancement, and jaggies, and motion etc. The PC realy isnt doing as good a job here

    Well it should do a good job, and whilst I do appreciate the finer qualities of the A11, I can't see it outperforming a HCPC set up correctly.

    Trust me mines set up properly, the only advantage i see is the 1:1 pixel map, hence all info is on screen with no overscan.

    where as i get a very tiny amount of overscan with prog out with the A11

    that said i have seen my A11 on my friends NEC HT1000 with both dvi and component and i`ll take the DVI pic anyday.

    Also have seen it on the pio434 and the difference was less obvious, maybe because of the tiny screen

    Other issues with the 434 m8, you can't do native DVI with it, it ain't possible. 433 it works very well

    I didnt think the A11 would be doing native on the 434 anyway,

    Or do you mean a PC on the 434? as an A11 wont work on a 433 cos of the HDCP thing
