    I wonder if anybody would share any knowledge on why DVD's sometimes drift out of sync.

    Is it the DVD player, or is it the DVD disc?

    I've used a few players and am pretty astounded (although now regrettably not surprised) when the audio track of a film drifts out of sync. Maybe it is the fact that it is such a simple function that makes it so infuriating and thus compels people to post threads like this. :mad:

    Anyway, based on my limited experience this horrific issue is quite common, and when I've performed a modest amount of research on a new player which i had planned to alleviate the problem, low and behold the new player has such foibles which negate the purchase, and the possibility of escaping the tedious situation.

    Cambridge Audio DV53, for instance, seemed like a fairly decent player - however, posts suggest otherwise. Audio drift is evidently again an issue. :eek: I'll add that to Samsung and Philips then.

    Surely, its all in my mind? - What say you, DVD specialists?

    :confused:

    Hi Nic

    Not a DVD expert by any means, however I did have a Cambridge DV79 that had lipsync issues and returned it and got a Pioneer 575, great picture and no issues so far.
    i have not heard of any on this model either frm looking through the forum so hopefully it will do the job for you.

    Great PQ and it wont break the bank worth a look IMOA

    Cheers

    Chris

    Cheers Chris,
    P 575 - I will take a look, thanks.

    Who would have thought that modern technology would be such an utter shambles? I'm not being trite, but I've never seen a Betamax cassette go out of sync.

    Cheers!

    nic - generally lip synch problems are caused by the fact that the picture and audio are being processed by 2 seperate components and as there is no link between the two one doesnt know how long the other is taking to do the job.

    The most common time this occures is with plasma/lcd screens as it physically takes time for the image to be scaled, deinterlaced and processed to show on the screen but the time it takes an AVR to seperate out the 5.1/6.1 channels and amplify them is significantly less.

    As this is such a wide spread problem many AVRs come with a lip synch correction option which will intentionally delay the sound by a specified fraction of a second to allow for the image processing.

    What you seem to describe however does not sound like the typical problems experienced as you say the sound occasionally drifts out rather than being a consistant thing - are you using an AVR for sound? what type of display screen do you use?

    I first noticed the problem with a Samsung DVD 709, which was simply piped into a normal TV. A lip sync problem through a UHF lead - beat that!. Aside from the usual time drifts, if we dared to pause a film, it spelt disaster, as re-playing meant sometimes a '1' second delay (no, I'm being serious). Turning the DVD player off and then on and then trying to find the location of where we paused the film proved fruitless.

    Eventually, we figured it was the player, and thus swapped to a Philips machine.

    And guess what ... Yep! ... that's right.

    Incidentally, we do now have an AV amp. and plasma screen; the sound broadcast through a coaxial cable, and vision through an RGB Scart.

    To say that I'm incensed by this is putting it mild. I won't mention the other special foibles the (brand new) Philips player boasts as I haven't got time today.

    You could say we've been unlucky with two different DVD players from different manufacturers but each time I commit a search for background info. on a new player ... guess what comes up!
