Layer break “layer breaks are one of those misnomers (an inaccurate name) that has grown out of IfoEdit identifying clock discontinuities as possible layer breaks, as an aid to splitting a DVD.
A clock discontinuity is when the system clock reference (SCR), a running value used for synchronization, has been interrupted. Most usually it has been set back to zero because the 2 pieces of video were encoded seperately. The last “phantom” chapter of many movies is an example of this. It also occurs during a layer break sometimes, which is where it got its name. Playback is not seamless over a discontinuity in a lot of players, causing a pause. If the SCR has been replaced with a new continously inceasing value, the marks can be removed.
The true layer break code, six or more sectors of all zero bytes, is removed by the DVD reader, and never seen by PC software.” –by mpucoder

Tip 10 Install an ASPI layer
To install extract all files then double click on INSTASPI.BAT
Once it’s installed just reboot your computer and it’ll be installed.
Many programs used to require an ASPI layer to access your DVD. However, nowadays most come with their own (Nero, BlazeVideo DVD Copy, CloneDVD, etc.) or use another method. So only install this if you encounter ripping problems.
