OK, to start off I have a Core2Duo 20" iMac. Everything has been great except for disc burning. I seem to get about a 50% failure rate with burning DVDs and it is annoying me. I'm not sure if it is the disc drive or the DVDs themselves. I am using TDK DVD+RW. These are the apps I've tried: Disk Utility: Works half the time. Toast: Tried 3 discs. 1 came out perfect, 1 didn't write properly but was recoverable after erasing it in Disk Utility and 1 was a coaster. Disco: 2 discs turned into 2 coasters. Burn: 1 disc that didn't write properly but was recoverable. Most of the time the errors seem to pop up during verification. Should I bother verifying the discs? Is the iMac disc drive picky with the discs that you feed it? Any suggestions on the brand of discs I should use would be great.
