    Capturing via Matrox Marvel at 704x576 (PAL) but on PC screen this is does
    not have the correct aspect ratio - everything is horizontally squashed very
    slightly. If played back onto a TV I think it is okay ... I assume because
    of the difference in pixel shapes or something like that.

    The PCVCR software that comes with the Marvel has an option for setting the
    picture to 4:3 but this is only on playback and I want others to simply be
    able to click on an mpg file and view it in mediaplayer without specific DVD
    software or PCVCR.

    Now I want to create a video that will be viewed on both PC and TV... do I
    therefore need to create a separate copy for each and could I resize it to
    the correct aspect ratio after editing via something like TMPGEnc? I think
    if it were the full 768x576 it would be okay. Would the 704x576 one that
    looks squished on the PC look distorted on a DVD player?

    TIA, Fred

    If you make a 704x576 DVD it will look correct on your TV. How it looks
    on your PC depends on the player or the MPEG-2 decoder. Windows Media
    Player can't play DVDs if there's no DVD decoder installed. It can't
    even play MPEG-2 files if there's no MPEG-2 decoder installed. So how
    your DVD will look on other people's systems is unpredictable. With the
    necessary software installed it will look fine, without the necessary
    software installed they won't be able to play it at all.

    If you play it full screen on your PC then the original aspect ratio becomes
    irrelevant.
