Do not know what happened to my reply...
Reply... The source code works fine with Encore but, I will take it back to a laptop or another station PC to test that again.
Are you clear of bugs to your knowledge, involving X64 and CD drivers? There are some issues involving driver signing and several of the software manuf. IE Roxio and others, for which a bypass of Vista check works fine, so I am wondering if there are other issues that could involve this software in the X64 bit enviro. and how it is finalizing disks... something appears to me to be related to finalizing of the disk, esp when I test it on other machines, most of which know there is data used but see the disk as blank... hidden.
BTW, your program's 'verify' function sees the disk as fine... verified and good.
