Smartburn and disappearing DVD drive?

After a recent crash I have rebuilt my PC with the latest versions of CloneDVD2 ( and Smartburn (3.1.8).
I am running XP XP Pro with a LiteOn 451s with GSB7 firmware installed.
Since updating I have discovered that after transcoding and burning a disc from an ISO file, I cannot read the next DVD in my drive unless I first close Smartburn.
Windows no longer recognises the drive as a DVD drive but as a CD drive - at least that’s what My Computer shows it as.
Has anyone else experienced this problem.

Try updating or reinstalling aspi or go to your bios and do hdd auto detection or reinstall ide drivers.
