Possible cause of some stuttering problems

[roux]

Hi all,

I was watching SWIII the other day and i noticed a stutter between scene changes halfway at the movie. This was really strange to me cause i always remove layerbrakes manually to make sure there are none.

So i take a look at the main movie pgc with ifoedit but i noticed there weren’t any layerbrakes of course. The exact location of the stutter is were the original layerbrake was. Only the problem has something to do with the vob-id’s.

As you can see in this image the vob-id’s aren’t following each other so i think the stand-alone player has to move the lens to an other location or something which results in a stutter just like a layer brake.

Therefore would it be possible for dvd-rb to rearrange vob-id's somehow?

Youre missing VOB id 4, that's strange.....

Did you have a look at the original DVD ????

But don't worry, the player is probably not gonna search for VOB ID 4, as it is simply not there, and the player uses other links to get the next VOBU (vob unit).

However it is strange, did you inspect the original ????

It's there, only in PGC2. PGC2 is used for the THX optimizer (it's linked to cell 32 in PGC1), you know when you've passed all tests the optimizer plays a scene from the main movie so you can check if audio and video are set correct.

That just means you probably did a "Movie Only" rip. So the largest PGC was used to create the new DVD. If VOBID 4 was a part of a different PGC, it wouldn't be needed. There is no requirement for VOBIDs to be sequentially used -- even though they usually are.

As an experiment, you may want to try this setting for REBUILD to see if the stutter goes away:
