You can link DVD-Video and DVD-Audio content by using multiple VTS sets and using a VGM menu to link them. The basis is to author one project first (DVD-Video usually), compile it, then import it with a link from the DVD-Audio project. You need software that supports this though.

*** You need software that supports this though. ***That's the real issue. I haven't come across documented evidence of an authoring tool that supports it. I've also yet to see hard evidence of an actual commercial disc that implements linking (as opposed to duplicated content).
I understand there's some fairly severe restrictions that constrain whether the link will work or not.
Neil Wilkes said the current version of Chrome should support it, but I asked him to do a test DVD to demonstrate that it works and so far haven't heard from him.
DVDLab Pro supports the importing of pre-compiled VTS content, but that would mean you'd have to author the DVD-Audio first, then the DVD-Video so that would prevent AUDIO_TS to VIDEO_TS linking, you could only do VIDEO_TS to AUDIO_TS.> I've also yet to see hard evidence of an actual commercial disc that implements linking (as opposed to duplicated content). <
There are a few, but I forget which. I seem to remember there were some discs with 96kHz PCM that was available to DVD-Video players that was actually in the AUDIO_TS folder so that it couldn't be ripped (prior to the DVD-A hacks). That at least cuts down on disc space to a certain degree, the two-channel content can be shared.

DVDLab (Pro) is a DVD-Video authoring tool - it does not understand the AUDIO_TS structure. Try it yourself - you cannot import any DVD-Audio content, not even unprotected ones.*** I seem to remember there were some discs with 96kHz PCM that was available to DVD-Video players that was actually in the AUDIO_TS folder so that it couldn't be ripped ***
I don't think this is possible, but happy to be corrected on this. The DVD-Video spec predates DVD-Audio, so there is no provision to link into AUDIO_TS content - and DVD-Video players do not contain the logic to parse AUDIO_TS.
All the discs that I've encountered so far with LPCM content on both DVD-Video and DVD-Audio turned out to be duplicates rather than linked content.
You can just import an entire DVD structure with any tool, only specific VTS sets. The key is to do that when authoring the DVD-A content. You can then link to it in DVDLab pro by writing your own links (just trying to drop an AUDIO_TS set into the program will not work, of course).
no, AUDIO_TS has a *different* structure - doesn't use VTS or VOB, therefore not recognisable by DVD-Video authoring tools.
