Similar issue
I am having the same issue. a commercial DVD, recognized by my macbook pro, and my xbox, and dvd player, but not on my macpro tower.
I have tried BOTH Drives in my macpro. both yield same result. I get the dialog box that says I have inserted a blank disc.
Computer Serial# is G87041ZZUPZ
Last I knew, the machine was configured to run the North America Region, which is where the disk is from. is there a way to confirm that is configured correctly? I have in the past done a complete reformat, reinstall, and upgrade to this machine.....
I am running MAC OS 10.6.4, and everything is supposedly up to date. I reset the SMC to yield no result.
The drives work to burn CDs, read CDs, and it recognizes the snow leopard install dvd with no problem. The drive shows up in disk utility, but with the Bon Jovi DVD, it alerts me that I have inserted a blank disk, and disk utility does show the drive, but not the specific disk. I have 2 drives in this machine, both "SONY DVD RW DW-D150A" Both are functioning in the exact same manner.
any clues as to what may be the issue here?
