I have done a fix for this. Creation of IFO files now uses a 
dynamically-resizable buffer, so you should be able to go all the way up 
to the limits of the DVD-Video spec.

Your control file has about 4000 <vob> lines in it. I successfully 
created a test with over 7000 <vob> lines, and the updated dvdauthor 
builds it just fine.

However, dvdunauthor seems to run into limits with libdvdread, I get 
repeated error messages like this:

*** libdvdread: CHECK_VALUE failed in 
/build/buildd-libdvdread_4.1.3-8-amd64-UYsyCI/libdvdread-4.1.3/src/ifo_read.c:1203 
***
*** for vts_ptt_srpt->title[i].ptt[j].pgn < 100 ***

So it appears somebody isn’t expecting a PGC to contain more than 100 
programs. :)

As always, my code is at <http://github.com/ldo/dvdauthor>.
