Re: Dual Layer DVD error

When using Mutli-angles you have to pay attention to details and I would guess by your post that is not a strong suit of yours (please don't take offense). Your title is "Dual Layer DVD error" and you post a problem about "Illegal angle situation"

With multi-angles you should always use CBR encoding. But the main issue that people run into is invalid GOP sturctures which gives the Illegal angle situation Every angles has to have every I-Frame is the exact same place. If you set chapter markers for one stream and not the other it violates this. If you are going from FCP timeline, if cuts are different on each angle it violates this.

Safest way to encode for multi-angels is to export each angle as a self-contained movie, with no markers. Bring both angles back into FCP and place them in V1 and V2 in-sync with each other. Then Export>Using Compressor with a CBR preset (you have to make one) use Closed GOP also.

Test this out as a simple multi-angle and then if it works add your markers in DVDSP.
