Re: DVD burning process.
You can do that but errors happen a lot more frequent, When burning a backup I have it make a copy onto my hard drive and then to the other drive, and either surf the net or play a game that doesn't need a disk in the drive. However I now have a 2nd PC just for that, so my main PC does not get tied up. But your best bet if you have 2 disk drives is to copy the ISO file to your HD and then to your disk, or you may risk burning a read error, putting it on the HD it corrects those errors before burning. and having two drives is faster and you don't have to worry about loading a blank disk if you walk away.
