libscg: I can't find it using "apt-cache search", and I think that it is 
used only internally by cdrecord. cdrecord 2.x is licensed under CDDL, 
so I think I can't copy the library into my GPLed software.

libdvdread: you may be right that it is only for video DVDs, I have just 
checked short description of package.

libdi: I can't find it in Debian repository, but I will look into it 
closer later.

cdrtools: in theory it might/may be possible to read content of CD/DVD 
with one of programs from cdrtools package, i.e. burn DVD disc and then 
verify it with by reading disc with cdrtools, but I can't assume that 
cdrtools is installed on user's system, next to growisofs. Sometimes a 
library is more convenient than a separate program :)

growisofs: grepping the source shows that growisofs has 
"-use-the-force-luke=wrvfy for WRITE AND VERIFY(10)" option. I don't 
know yet how it works, but it may be worth checking.

I'll wait and see. There are some possibilities to check and explore.

Kind regards,
