Help, I'm trying to burn 4.7 GB DVD+R discs using Nero 18.104.22.168, on Windows XP Pro SP2, and I don't want to burn the whole DVD at once, I want to keep adding a few files at a time. The only problem (and it's a big one) is that I tried several times to create a second session and it always makes the first session hidden and invisible, so I lose access to that first set of data, why is this? I tried creating the disc as a DVD-ROM (ISO) or DVD-ROM (UDF), but both types give the same problem. I only see the latest session when I browse the burned DVD in Windows Explorer. What's up here? Have I lost that previous data for good (I hope not) or is there some program I can use to be able to access it? More to the point, how do I stop this happening again? I want to be able to add data whenever I like to the DVD so it fills up gradually and I can see all the files from the oldest to newest. I know this should be easy, but I can't figure out why it's going wrong. Help please!
