Seems like you've either got bad disk(s) or a hardware problem if it persists across brands. I haven't ever had a problem reading a disk that I burned, even the off brand disks - but some of the cheap disks have not been readable in other computers and DVD players. Verbatim disks seem to work fairly reliably, and Apple disks seem best. SR
