I've experienced lip sync problems with some dvd's on different players. Is
this usually a fault of the player or the dvd?
Are there adjustments?
thanks,

Could be either or both. This is a well known problem that affects many
dvd players, cheap or expensive. It is generic to DVD I think. Some
people say it worse with digital audio than with analogue.

There are multiple factors.

1. The player. Just Google and you will see that many brands are said
to have this problem. Sony, Pioneer, as well as unknown brands.
From a review at PriceGRabber for the Panasonic DVD-s52

The main key feature that made me keep this DVD player is the audio
sync delay function. This lets you delay your audio in 20 ms increments
anywhere from 0-100 ms. This is useful because with my Samsung DLP, the
video is delayed slightly, such that I notice lip sync issues when
running the audio straight to the receiver over digital coax.

With the delay set to 60 or 80 ms, I don't notice any lip sync issues.
I don't believe any other DVD player under $200 offers this feature.
The Sony NS-75H claims to have audio sync delay, but it only works on
the analog audio outputs, which are useless if you have a home theater
and want to run DD or DTS to your receiver. This audio sync delay
feature along with the nice user menu made me keep this DVD player.

2. The movie itself. Some movies are just plain out of sync to begin
with, and the DVD reflects this. Lost In Space is an example.

3. The DVD iItself. Pioneer DVD players and Village Roadshow DVDs are a
potent combination, and frequently exhibit this fault, though the same
player playing other DVDs will play them without a problem and
conversely the same DVD played on another player will also play back
without a problem.

4. Firmware revision. Sometimes updating firmware can make a
difference.

4. Individual sensitivity to the problem. Different people are more or
less sensitive to this problem. Personally, I pick it every time and
find it extremely distressing, whereas others watching exactly the same
disc at exactly the same time either notice nothing or barely notice
anything wrong.
