    OK, quick Stoopid question...

    I get serious screen flicker (unwatchable) in my old TV when playing certain NTSC DVDs on my Marantz DV6400 SACD/DVD player. Its a really old Pal TV, and the dealer says that's my problem and I need to upgrade my display to something that can handle NTSC. I figured the DVD should be able to downscale to Pal, but I guess I'm wrong.

    So, is this a problem caused by a 60hz signal going into a 50hz capable device?

    Dum question I know. Sorry... :blush:

    Wrong forum. But to answer:

    (Regular definition) TV signals come in two fundamentally different structures:

    625 lines (of which 576 are used) and 50 fields per second (hz). This is the structure of PAL as used in the UK.

    525 lines (480 used) at 60 hz. This is the structure of NTSC.

    If the TV won't handle 525(480)/60hz then you get a wholly unwatchable result.

    Solutions:

    a) a new TV capable of 525/60.
    b) a DVD player that fully converts NTSC disc sources to PAL, 625, 50hz. Very few do this, and those that do, don't do it at all well. Those that do are typically the cheapo chinese ones sold for a few tens of pounds in supermarkets and the like.

    Thanks guys,

    Figured that was the problem. BTW, couldn't find an appropriate forum to post this under tech talk. Should have posted in the display area I guess.

    Thanks anyway...
