The reason I bought the new drive was because the same message was happening with the Liteon drive with the PowerDVD 7 software it came with. I thought if I bought a new drive with new software it would take care of the issue. But the Liteon drive doesn't work with either software PowerDVD 7 or 9. (DVD 7 completey removed and DVD 9 now installed) I have read several posts with folks having the same issues but nothing really getting resolved. I put in a support ticket in to Cyberlink and I am waiting for their response. Does ayone know of a fix? I dont see how a critical update is missing if one drive is working fine and the other one isnt. Not mention the Liteon drive works perfect as a regular drive. You can put any Blu-ray in an then go to my computer and see that the name of this disk and the size of the blu-ray. I thought it may be a firmware issue but not leaning that way anymore seeing how the blu-ray advisor program shows both drives and say they pass for blu-ray playback. Any smart guys out there with similar problems? Thanks Eric Tanner
