Hi:
If you can read and access the files on a DVD media, and have the latest
version of the firmware for your LG DVD, I understand that it could be a
software problem. Try with another sofware other than Powerdvd. Did you got
a copy of any DVD software with your laptop? Do you gt any error comming
from Powerdvd, when try to play the DVD?. I am sorry I can not be more
helpfull.
