Sony 735 Layer Change.

I ve just bought my first two dvds, Gladiator and Braveheart.
I was worried when both of these discs pause for a second and then start.
I thought I had faulty discs or the machine was faulty. I ve just been told that this is the "layer change" ( not sure what this means ) , is this change as noticeable on other machines and do all discs have this?
Thanks.

I suppose in the spirit of things I should get to you before The Ironduke does..

The layer change is somewhat slow on all sony`s but don`t let that tear you away from the point of why you bought the player.

To watch fantastic Video & Audio performance come out the back and into the TV and Amp you have connected to it.

Don`t be fooled by these people who say this that and the other. If you satisfied and can live with the layer change, is not bad on all disc`s I might add, then stick with otherwise get something else....

Personally for a budget player my 336 is just fine...

Most DVD movie discs have a single-sided dual layer configuration, meaning there are two layers on the `bottom side` of the DVD (the side without the movie title and so on).

The first layer is able to hold 4.7GB of data which is seldom enough for a high quality 2hr long MPEG2 encoded movie. So a second layer is introduced which can hold an additional 3.8GB of data. The first layer is semi transparent and gold in color. (that`s why our two-layered DVD movie disc looks like a gold disc but yet not quite) And the second layer which is hidden, is silver in color. The two layers are bonded together by a unique Ultra-voilet adhesive bonding method.

Now coming to the layer change issue here. When the laser reaches the end of the first layer, it increases in power slightly in order to penetrate the first layer which is semi-transparent and begins to read the second layer. This layer change would introduce a slight pause to the movie and the duration varies from around half a second to a second on most players.

One thing i like to point out is that, this layer-change-pause is usually not noticeable on DVD-ROM drives. When you play a dvd movie on a reasonably fast computer with a 4x or better DVD-ROM drive, the layer change is almost seamless. This might be due to the fact that computer systems have comparatively better data buffering.
