Package: dvdbackup Version: 0.1.1-10 The attached patch makes it possible to read recent dvds which contains half broken IFO and full broken BUP files.
Half broken IFO files: Wrong filesize in the UDF. Fixed by using
ifoOpen and the filesize from the open dvd file handle. libdvdread was
fixed recently to update that size to a sane value.
Full broken BUP files: Missing or completely bogus sizes/contents. Fixed
by always recreating it from the corresponding IFO file.
It have one problem. If the IFO file is in fact bogus in a way
libdvdread would reject it, it bails out.
