/**
* Generic verification job. Add tracks to be verified via addTrack.
* The job will then verifiy the tracks set against the set checksums.
*
* The different track types are handled as follows:
* \li Data/DVD tracks: Read the track with a 2048 bytes sector size.
* Tracks length on DVD+RW media will be read from the iso9660
* descriptor.
* \li Audio tracks: Rip the track with a 2352 bytes sector size.
* In the case of audio tracks the job will not fail if the checksums
* differ becasue audio CD tracks do not contain error correction data.
* In this case only a warning will be emitted.
*
* Other sector sizes than 2048 bytes for data tracks are not supported yet,
* i.e. Video CDs cannot be verified.
*
* TAO written tracks have two run-out sectors that are not read.
*
* The VerificationJob will also reload the medium before starting.
