Safe to layer break at an "LU" sector?

[Peppero01]

Hi, I've been using PGCEdit to make my ISO's and was just wondering if it's okay to make a layer break at a cell that is labeled as "LU" (language unit).

[LIGHTNING UK!]

Blu will help with this I'm sure, but you're probably better off asking in the IFO Editors forum at Doom9.org !

 

Out of interest, is that the only option you're given?

[Peppero01]

Well, no--according to PGCEdit, that sector just happens to be nearest to the "optimal" LB point. Me, being wary, did not use it as a LB on my first burn, but instead used the sector below it (which was a segement of video showing the "FBI Warning" and NOT an LU). However, this caused 2 coasters with an I/O error. So this will be my third attempt and here's hoping I pick a LB point that will burn. If this one fails, I blame it on the media

 

Edit: And just for reference...

I very much doubt the I/O error is anything to do with the layer break position.

 

Post the log so we can see what's happening and what the exact error was.

[Peppero01]

Sorry--I didn't have a chance to save the log as ImgBurn locked up both times the error was displayed. I was also thinking the I/O error couldn't have been because of the layer break point, but I just re-built the ISO with PGCEdit, selected a different point to break the layer, and it's been (so far) burning fine--if it errors out again, I'll make sure to post the log. But, for now, I still think it's the media I'm using that's causing the I/O. RiData isn't the most reliable--they were bought by a friend of mine when I specifically asked for Verbatim (oh well). The LU breaking point was more out of curiosity because I'm kind of wondering if putting the VTSM 3 LU on one layer and then putting the rest of the VTSM 3 files on an entirely separately layer will cause any issues.

It's very rare for the entire program to lock up, most the code is done in thread - especially the burning stuff - so the GUI one should always be responsive.

 

Did you have to terminate the process or something? Maybe even do a full reset of the comp?

[Peppero01]

Nothing as drastic as resetting or terminating. I just chose to "End Task." Anyway... the third burn did wind up erroring out. Except, this time, I got a completely different error. The burn finishes, but it can't close the disc and I get this:

 

"Finalise disc failed!

Your choice of media is part of the problem Peppero01, Verbatims are the only ones we have had consistent success with here. Ritek was good media, but they changed about 18 months ago and now are very problematic.

before you make yourself nuts trying to see if its a software problem get Verbatims because like its been said Ritek has ben going down the tubes

Sorry to take a while to respond. The LU is simply a designator that there may be additional LUs on the DVD. There is no issue in breaking at, or in the middle of, any LU. For mine, however, I would always try to break at the start of a title - this is the natural place because there is always an STC discont and a non-seamless joint (in your case, you have title 4, 5 or 6 to pick from).

 

Although, some would also say that it's a good thing to have a whole VTS on a single layer (so there's no swapping back and forwards across the LB when a menu call is made). So, 6 of one ....

 

But, don't be afraid of breaking at the start of any LU (you can use PgcEdit to eliminate unwanted LUs if you like - Menu --> Remove LU).
