Okay I can confirm this behaviour. As long as there a blanked streams which
aren't at the end and RB shows them as unreferenced, RB crashs with a runtime error 380.
I've made four tests with a movie which owns three audio streams (engl. and german AC3 plus german DTS).
Blanked the first stream with DRM => RB crashs
Blanked the second stream with DRM => RB crashs
Blanked or deleted the last stream with DRM => Audo
track remapping worked.
Workaround:
1. Don't blank audio streams with DRM...
2. Open the blanked DVD in PgcEdit => doubleclick on your main movie => under audio streams chose the one which is marked as "none" => change the value to an existing stream. You can even set it to the deleted stream number and remapp it later with RB.
Edit: Tested the same with Vobblanker: Blanked everything except the main movie and stripped two audio streams => Audio track remapping works because Vobblanker doesn't change the stream infos.
