    Now, you see, there you go again!! I spend all this money on getting a filmic quality presentation at home and then somebody points out all the flaws I have spent time managing to forget.

    Now I've got to get out the Teddy again, where are you Mr Burplepus?

    What's that mother? Oh, yes, coming mother.....

    Funny you sould mention "EE".
    I have been tweaking the settings on my Vw10ht using Video Essentials etc. I found the sharpness setting to be perfect. Ie i left it set in the middle(50).
    I then tried several Dvds to test for colour/brightness/contrast etc.
    When i started watching the "Wild-Wild-West", i started to notice EE.
    Were Will Smith gets off his horse and walks up the white houses path his black pants show big white halo-ing (ringing).
    I thought it may have been my projector etc.
    I rechecked with V E and again perfect.
    But your link has explained all!.
    I had assumed any EE was added by the dislay device.
    Excellent link, cheers mate :)

    Fascinating article. Thanks for the link.

    Now it is time for all Magazine Reviewers to start giving "points" for the film transfer, based on viewing on a very large, reference quality, front projection system, rather than the 24" TV many seem to use.

    Very interesting. In the same way that Jenz' recent article comparing R1 and R2 (using The Fifth Element) has dispelled some notions, this article would suggest that anamorphic does not necessarily lead to a more 'watcheable' picture.

    Used to have a lot of problems with EE on video land effects work. Now ensure I forbid the telecine operator to apply any filtering whatsoever.

    Not nice when you pull a key and get a big white/black edge round everything then the client comes back and assumes its your problem. tsk!

    bh said, "....this article would suggest that anamorphic does not necessarily lead to a more 'watcheable' picture. "

    Like everything, each factor has to be considered "all other things being equal".

    So, Anamorphic DOES mean a more detailed picture "all other things being equal".

    PAL should give better resolution than NTSC "all other things being equal".

    If all other things are not equal, comparisons based on assumptions like these don't work - "it's PAL so it must be better than NTSC" isn't true because other things aren't equal.

    This is why the theoretically better PAL version of The Abyss is pants compared to the theoretically worse NTSC one.

    Very interesting Neil,
    This was one of the few things that vexed me when I moved up to a projector. When I changed from S-V to RGB though, ringing vitually disapeared. Any theories as to why anyone?

    Edge enhancement isn't just on DVD's. Over here they add it to television programming on some channels.

    Watching hockey or golf they whack it up so you can see the puck or ball more easily when it's flying around the screen. Nightmare!

    Could be an SVM (scan velocity modulation) circuit in the composite paths in the projector. RGB should bypass this.(as long as its not screwed with in an additional sampling stage)
