how do DVDs continue playing from before ?

[rh71]

... cause I can eject the disc, and throw it into another player, and it'll play from where I previously left off. I thought these were DVD Read-Only...

 

[Fiveohhh]

Never had it do that for me....I honestly don't see how it is possible

 

[bandana163]

I'd like to know the answer as well.

It does that all the time by me. Power DVD asks me if it should start from where I left off last time. Even if I say yes, it doesn't always work, but it usually does.

I've never got that lucky with switching out and all.

 

[thejackal1]

maybe the dvd software can remember the place where it stopped. This is on a comp though.

wait a minute, you're saying you start to play the DVD in one machine, take it out partway, and put it in a DIFFERENT machine and it plays from where you stopped?

Doubt it...

If this is what it is... I call BS.

No, same machine.

Ummmmmmmm.. Maybe the drive has a buffer? And it also stores the DVD id in it to know where it left off last?

Even some set-top players remember a location, though it's usually lost if you put in a *different* disc, then eject and place the 1st disc back. If it appears to start in that location on another player, I can assure you that it's because you stopped there on that player. The DVD did not retain or transport any dynamic data.

well the software stores a small database of what DVDs you have played, and if playback gets interrupted the next time you insert the DVD it asks if you want to resume.

on a computer it can store the place you left off and start again even over multiple ejects

on normal set top boxes, if you eject it usually cant start from the last place but it still keeps the last location in a memory bufffer.


its the player that saves the information in memory, it doesnt write to the disc.

stores position on the disk.

the only time anything like that happens to me is if i go to the menu during the movie, browse around it a little bit and go back and hit play movie it goes back to where it was.

 

[gopunk]

doesn't seem like it is that hard to implement... just store movie/dvd-unique identifier and position in some sort of table.

This is exactly why I brought up the question. I can understand how it works (thru software) if it was the same machine. But I ejected from my PC and threw it in a Sony set-top and it played right where I left off. I was like.. HowTheFvck...

Shenanigans!!!!!
