I am wondering, is this navi=lba+0x40000 behaviour consistent for all the 
error messages?

Maybe it is just a weird flag that all players choke on, but could be 
ignored (i.e. masked out). I don't know. Maybe add

d->dsi_pack.dsi_gi.nv_pck_lbn &= 0xfffbffff;

before the check in libmpdemux/stream_dvd.c (line 273) and see if that fixes 
anything. But even if it works, this is probably not the right fix :-)
