In regards to this change in the 1.05.2 build of DVD-Rebuilder Pro: Code:

Yes. You can just REBUILD. But I don't think there would be a relationship to "not playing reliably" -- if there was a difference as all it would only be a very slight pause (more like a "tick") at the layer break (exactly as you would have seen on the original as it changed layers). Removing that "tick" is all that layer break removal accomplishes...

Nothing has changed in that regard... try another title.

I went ahead and added the AGGRESSIVE_LAYER_BREAK_REMOVAL=1 to the INI file and rebuilt it. I burned it to DVD and now it works fine on both DVD players. Glad I didn't have to encode it again. :)

Not that I have to agree with JDOBBS at any time, any place (he's getting sick seeing my name only :) , but I have to agree on this one with him. Layer Break issues will be noticed as a puase or skip for just one moment (m ost of the time a little pause) I stick to JDOBBS and I think some other factors are of importance here. Media used, quality of burning, etcetera. As a player WON'T scan for the layer break in advance, it can't be saying TITLE NOT FOUND or NOT PLAYABLE when inserting it. It will NOT search for the layer break in advance.

If you are worried, check for, and get rid of, the LB in . Open the DVD in PgcEdit, double click on the movie PGC and scroll down to the cell with the LB in the middle of the title. Untick it. OK. Save and burn. Total time taken = about 20 seconds. No need for rebuild at all since the LB is in the IFOs :) Regards

or if that is too difficult don't forget DVDShrink and pass it through...it always gets rid of layer break.

Remember not to call me, though, if you have a Sony player... I compared the output of the layer breaks removed by Shrink -- and it seems to use the exact same methodology as DVD-RB in aggressive mode.

So if anyone wants layer break removal to operate in the same manner as DVD Shrink, which is the way RB worked in prior versions, they need to change the INI for AGGRESSIVE_LAYER_BREAK_REMOVAL=1? Correct? Wondering what exactly the new "less aggressive" method is i.e. how it changes the flags--can someone explain?

Generally what is done in removing "Layer Break" is resetting the seamless playback flag in the cell playback information table at the point where the layer changed. Most methods used by DVD copying software (if you search here on DOOM9) simply reset the flag. But... there are some rules as to what can be considered seamless that can be violated when you do that. Often when there is an SCR discontinuity and the the SCR is restarted at zero (and possibly even when it isn't) you will find that the audio of the last cell of the first layer is padded. When this happens you shouldn't reset the flag, as the stream is not truly seamless. Most DVD copy programs appear to just reset it anyway -- and virtually all players will just play right through it. Some players, though, are a little more finicky and choke when this happens and "glitch" during playback... When you select "aggressive" mode... it will change it anyway. Non-aggressive follows the rules and leaves the seamless flag off under these circumstances.
