in libcdio a bunch of information is kept private and not readily available to programs, what I'm concerned about is basically the start/length of a file.

this is in the udf_dirent_t structure, but is hidden from programmers.

I care about this as I am trying to write a barebones dvd decrypter that works on images files

i.e. I have some DVDs in bad shape, so using 1) lsdvd to authenticate the disk, 2) ddrescue to recover a complete image, but it still has CSS embedded, so then need to remove the CSS, but I have to basically check if I need to rekey on each VOB file and need to know the start of it to rekey on the right block. libcdio's udf support should provide it to me, but as it's hidden, it doesn't.

any thoughts on providing an interface to this data?
