Sometimes I like to make another copy of my backup but after upgrading to Nero 18.104.22.168 I find it does not finish the job in 'on the fly' copy mode. I have no intention to upgrade to 6 so please don't suggest this. In other words it does not copy directly DVD's anymore. Anyone no why? OK I can still rip to HD and then burn, which is fine, but sometimes I need a quick copy. Used to be 100%.
