He's right you really should head the rules it will be less headache for you later and you should stick to personal back-ups only...Rules asside I've had a similar problem, it is most likely your burner. I've tried just about everything known to man in fixing this issue. Its not your software its probably outdated firmware and an old drive. However if you have a new drive and this is an issue it is probably just your firmware. Furthermore if the drive is both new and the firmware is up to date...well I'm really stumped. All I know is that not everyone has this problem and purchasing a new drive is cheap. So if all else fails and you get upset enough (like I did) just by a new drive its like $40.
