Dual Layer-Opposite or Parallell in Scenarist....

Sup guys!
I wanted to know which one would be better, Opposite or Parallell on my dvd9 project? The project contains music videos.4-6 mins. long (each song, for each chapter). I know one of them has a delay about 0.5 sec in the middle and it has to do something with how the laser on the dvd player reads the layers on Parallel or Opposite. Well I can put the dual layer cut at end of a song (so it wouldn't be noticeable). right? ....So which one should I choose?
Thanks!
I'd appreciate your Advice!

It is always better to use OTP (Opposite Track Path) if your project is DVD-Video (i.e. you're gonna play it in Standalone DVD Player). If your project is DVD-ROM then it should use PTP (Parellal Track Path).

Hope this helps.

DIRECTLY from the Scenarist manual:


[[14.6 Setting the track path:

You can select a Parallel or Opposite track path in the Dual Layer Editor's Type area. The track path is the direction in which the DVD player drive head reads the disk. The track path can spiral outward from the area near the center hole to the edge of the disk, or from the edge toward the hole.

The drive head always reads Layer 0 from the inside out. If the drive head reads both layers from the inside out, the track path is Parallel. If the drive head reads Layer 1 from the outside in, the
track path is Opposite.

A decision to use a parallel or opposite track path for a dual-layer disc depends on the amount of material you are putting on the DVD and how you want to arrange it. There are two factors that may influence your decision:

* Playback between layers is always non-seamless; there is always a pause when the DVD player drive head transitions from Layer 0 to Layer 1. With a parallel track path, however, when the drive head reaches the end of Layer 0, it has to move all the way back to where it started before it begins to read Layer 1.

* An opposite track path has the constraint that layer 1 can be no larger than Layer 0. If Layer 1 contains more information than Layer 0, scenarist alerts you to the fact during premastering. you could then delete some files, or open the Dual Layer Editor and select a parallel track path.

N.B. Only ONE layer of any dual-layer disc can contain both DVD-Video and DVD-ROM files.]]

Thank you very very much bros!!!
I appreciate it!
So I'll go on with the Opposite since my project has no DVD-Rom content, just DVD-Video.
