Setting layer break on an IFO/BUP file

[dbminter]

What exactly happens when you set a layer break for a DVD Video on an .IFO/BUP file?  For example, if you set a layer break on an .IFO and didn't use a seamless layer break, would you still get a layer break playback pause anywhere in the video?  What if you set a layer break on a BUP?

 

Thanks!

if it isn't in the middle of a video stream (which of course, IFO and BUP aren't), there's nothing to make seamless.

Thanks!  I wasn't sure if, somehow, choosing an IFO might place a layer break pause somewhere in the video referenced in the IFO.  I didn't think it did; particularly why I always choose BUP if offered.
