I have used Nero 7 for a long time and burned lots of Multi session DVDs. Ever since I have installed SP3 for my Windows XP Pro, some of installed software on my laptop started to behave differently, first it was DAEMON tools with registry error message whenever mount the disk and now Nero.
Here is the issue, I have noticed that Nero complains about the DVD is not writable for a DVD-R that burned as Multi session with same drive HP writer dvd630e and same result using my NEC writer on my laptop.
I have tried it with different DVDs but same result. No matter the selection it seems disk been burned single session. But here is the weired part, when I use the Disk Info under Recorder in Nero, it displays session info but when I tried to continue on burn meaning adding filed to it, it says disk is not writable. It seems Nero can read the recorded session info but cannot use it to add file to new compilation.
I have tried to update firmware for both writers but no new firmware found. I have upgraded to Nero 8 but ended-up with same problem. I have tried different DVD-R but same. I have read some comments about ASPI Layer but I don't believe they are for burning and no need for Win XP.
I know what caused it which was Windows SP3 but don't know how to fix it.
Simple solution is not to use Multi session but I do have accumulative backup of my files on computer and cannot possible waste a DVD for each backup. I know that issue that most of Divx players have with Multi session disks but in my case I am using the same burner attached to computer.
