Sony vaio crx810e won't play some burned dvds


I burn dvd +r using both dvd xcopy and also dvdshrink. The dvds I make with xcopy work on every standalone dvd player and ever computer i own.

My sony laptop however with the sony cd-rw crx810e drive will only play the dvds made with xcopy. Disks made with dvdshrink and burned with nero won’t play on this only machine.

Any help would be appreciated.
