Hi All,
(I tried posting to the Disc-Recording List, but no replies.)
I have been troubleshooting an issue where I burn a DVD and the burn
process happens, but the resulting disc is unreadable once burned. I
insert the disc after burning and I am told it is unreadable.
This never happened except on Leopard.
I am doing something similar to the following:
[burn setLaunchPath:@"/usr/bin/hdiutil"];
[burn setArguments:[NSArray
arrayWithObjects:@"burn",imagePath,burnVerify,@"-speed",burnSpeed,@"-
verbose",@"-noforceclose",@"-device",drivePath,nil]];
// And release the DRDevice here, just in case another application is
holding it reserved.
[[DRDevice deviceForIORegistryEntryPath:drivePath]
releaseExclusiveAccess];
[[DRDevice deviceForIORegistryEntryPath:drivePath]
releaseMediaReservation];
[burn setStandardOutput:pipe];
[burn setStandardError:errorPipe];
handle=[pipe fileHandleForReading];
errorHandle=[errorPipe fileHandleForReading];
[progressMessage setStringValue:
NSLocalizedStringFromTable(@"BURN_DIALOG_11_KEY", @"Localized", nil)];
[NSThread detachNewThreadSelector:@selector(copyStdOut:)
toTarget:self withObject:handle];
[NSThread detachNewThreadSelector:@selector(copyStdErr:)
toTarget:self withObject:errorHandle];
[burn launch];
Can anyone provide advice?
Thanks!
-Jason
