PgcEdit trace hangs on playback of Previews

[notec]

Ok, so I've got this project where I've had to Jump to the Main Menu on DVD insert because its sharing the "Coming Soon to DVD splash" and if I Kill it so goes the Previews...

When I run the trace and get to the preview button and select it it starts but then hangs:

******* Start playback VTST 3 , 1 TTN 1 (0:11) 1b. Title 3...
******* Playing Program 1, Cell 1 (0:11.00) (Chapter 1)
-> sprm(7:Chapter number (or PGN)) = 1 (0x0001)

I stop the trace and save. It plays back fine (no navigation issues) in MPC.

I'm curious as to what Pgcedit is hung up about?

I've included the complete trace up to the point the hang...

If anyone has any feedback as to what might be happening I'm all ears...

Can you see the preview window? How does it hang?
Does the trace work correctly with the unmodified DVD (before using Jump2PGC)?

Yes, the preview window does display - but only the VTS 3 (Title 3). But clicking ->> Next PB - It never moves past this point (See attached screenshot).

In the Trace Menu the Title, stream, angle and chapter info appears to hang at this point I left for several minutes before stopping the trace. This behavior gives me a false negative - as upon saving at this point it played fine in MPC.

I burned to disc and it plays the previews fine.

After entering:

VTST 3 , 1 TTN 1 (0:11) 1b. Title 3 - Chapters: 2, Programs: 2, Cells: 2

it never seams to link with the preview titles:

- VTST 4 , 1 TTN 1 (6:27) 3b. Title 4 - Chapters: 4, Programs: 4, Cells: 4
- VTST 5 , 1 TTN 1 (4:57) 3b. Title 5 - Chapters: 4, Programs: 4, Cells: 4

So, I don't know why PgcEdit doesn't make the connection? Something in the post commands. Dunno... hope that helps I'm hoping to know what to look for in the future when if this happens again and feel confident that I'm not burning a coaster.

Oh, and the trace behaves the same with the unmodified source.
