Programs that depend on specific Linux behavior tend to be non-portable (see e.g. nautilus on GNOME). Nautilus tries to get e.g. the drive write speeds by reading /prov/scsi/******. Besides the fact that this is not available elsewhere, it gives incorrect results because there are a lot of DVD writers with broken firmware. Cdrecord implements workarounds for this kind of problems and for this reason, the most portable solution for a GUI is to use cdrecord to retrieve the information.
