Well certainly for a long time the kernel would read past the end of the
device on many ATAPI cdrom drives.  Not sure if it applies to DVD at
all.  Basicly the kernel would try to read 64k at a time even if you
didn't ask for that much.  Perhaps the error recovery has finally
improved.

On scsi interface cdrom drives I don't think there was ever a problem.
