layer changing

Just curious what other people have experienced. I have had 3 DVD players so far. My first, still in use at my brothers, was a pretty low end Toshiba i think, honestly cant recall, but I loved it. had the best frame by frame i've seen so far.

My 2nd was a Thompson model, and my current player is a sony.

My question is this. On the first 2 players I can't recall any hesitation or notice of layer changing, but on the sony, no matter how invovled the disk is, meaning DTS sound, and things, There is a always a noticable layer change.

Is this the norm? Or is this something thats happening with newer players out there. Just curious, I can live with it as long as I dont have to get off my butt and turn the thing over myself. hehehe.


I dont have the exactly models to mention here, but i guess I'm asking is there a norm out there for this. The sony image is much better than the Thompson even on our Thompson screen, but I liked the Thompson better but I dont recall it being DTS, I have to check. It is also still in use but it was given away.

Almost all players puase on dual layer DVD's. Some more then others. I think the reason you notice it now is that almost all DVD's are dual-layer to pack in the features where the used to have single layer back in the day hence no layer change.

yup, but there is definitely a way noticable difference on the newer machine. It was worth the upgrade i guess but was just curious. I can take the same disk to the old machine and the layer change is almost not seen.

Was just curious.

It really depends upon the player. I have used some players where you don't notice the layer change at all and others where it was very obvious.

I've had 3 machines all Toshiba, 3008, 2109, and 5109. I would have to say they all handle it about the same. Noticeable but tolerable.

Anyone know why DVD player manufacturers haven't worked out some kind of memory caching system to overcome the layer change delay? One would think this would be a no-brainer. (No-brainer that we would want it... not in actually producing it... )

Perhaps it would require a good sized RAM cache (1 - 2 gigs?), but I would think the technology would be relatively easy to impilement, no?

I've wondered that myself. By the way, it would only have to be a few meg. A whole DVD is only 4 - 9 gigs.

Denon's current line of DVD players are equipped with memory buffers for exactly this purpose.

I have to check the specs on our Thompson model, it must have had this feature too.

One of the reasons I think my next player will be a Denon. Seriously wonder why no other manufactures have caught on to this.
