real-time layer change detect?

tao101 · 5th February 2014, 21:04

Hi. New here. I have a big DVD collection and am very technically inclined, but know only the most basic details of the underlying disk structure. I decided recently that this has to change, and have started downloading various editing and ripping tools.

There will be many more questions coming, but here's an easy one. I am looking for a player or a tool that will tell me exactly where the DVD layer change occurs (i.e. track and H:MM:SS), either through a debug stream or some kind of scanning tool. I thought VLC might do this, but I'm not able to get its log feature to write a single line. I found an older thread here (http://forum.doom9.org/showthread.php?t=123204) that might be enough...if I knew where to look in PGCEdit. So can anybody give me a straightforward answer? Thanks.

PGCEdit: Doubleclick the longest VTST. PGC Editor pops up.
Scroll to the cells in the middle. One is different.
Layer break occurs at this cell boundary where the following cell type flag shows 2 or 3 for byte 0
Discontinuity, no seamless. Cell duration time and end time are in the column to the right.
You will want to read the end time of the previous cell.

Realtime is much too slow ;-)

Thanks. I found everything you described, but was hoping for the exact H:MM:SS where the layer change occurs. What I have now is the chapter, which narrows it down to a roughly 8 minute segment. In a way this does answer my question (I am trying to differentiate between possible PI problems on the disk and a layer change stutter), but is there a way to be more precise, either with PGCEdit or some other tool?

The time is printed out in PGCEdit:
