    No, not a new socialist party.

    I read a post by Brajesh Upadhyay (hope I spelled your name correct) recently and he illustrated a shortcoming of a dvd players ability to show the colour red. The topic of that thread is a particular model of Denon and not the phenomena itself which I'd like to know more about.

    Can someone enlighten men on this topic? I am a huge animation fan and notice in some of the W.B. cartoons I buy on DVD (Batman and Justice League) some colours come up very pixilated and movement in some scenes is very choppy as if I'm watching framerate drop dramatically, but only in some scenes.

    Is this a shortcoming in the DACs being used in the DVD player? I have an Xbox as my DVD player. Someone tell me that I get this because the Xbox sucks as a DVD player (please?). I initially dismissed this phenomena as a poor job by WB in the transfer but I would be happy to hear it might just be my gear. I want to buy every W.B. DVD of Batman Dark Knight animated series and Justice League, I plan on buying a real DVD player soon and hope I'll get better framerates and fuller colour when I do.

    Thanks for any information.

    In the following thread:

    Dan Hopkinson says:

    "I have it all hooked up. I was wondering how to check for the CUE error, I have an RP-56 so I guess I never had it before. But if someone lets me know what to look for (I'm too lazy to search for what to check) I'll run the tests and post them later. I have the Toy Story Box Set, I believe the test is in there in the credits or something."

    Eluding to a cue error.

    Brajesh Upadhyay says:

    "Dan, put in the "Toy Story" DVD & look at the reds in the menu. The reds should be solid--no horizontal lines or smearing."

    And shows us the following image illustrating exactly what I get but worse using the Xbox as a dvd player.

    So, this would be the chroma bug? Can anyone say anything else about is there somewhere I can read up on it? Is it caused by inferior dacs?

    Thanks for any word.

    It's a well-known fault on many players, due to their use of the same buggy MPEG chips. It was discovered by the good people over at Secrets of HT and HiFi; you can read the latest about it straight from the source.

    Thanks for the link. I found this soon after posting the message, I started playing with the URL to the jpg I posted.

    Very interesting. The link even includes a list (slightly outdated I believe) of all a bunch of DVD players that have the bug and those that don't.
