You need to provide details, what kind of tools are used by you, how you doing things... currently only, a working crystal ball can help to solve mystery.

Yes.
1. How did you demux?
2. How did you remux or reauthor?

1. I would demux using either DGIndex (File->Save Project and Demux Video) or PGCDemux (needs the IFO).
2. I would reauthor for DVD with Muxman, for MPG using ImagoMPEG-Muxer.

If those don't work for you, then how was this DVD created in the first place, that non-standard assets were allowed to be authored?

I have resolved, the reason is that I use the old demux program. Thanks 2 bro.
