It's the 2nd time this happens, i was burning a DVD and 14.5 hours later it was still burning and the light on the drive is still flashing, but I then noticed the brunign had stopped around 80% and Nero never gave an error and the only way to get the light to stop flashing on the DVD writer and to unlock the door is to power off and back on.

The DVD writer has the latest firmware, what could be causing this? It is a Sony DRU720 IDE burner.

Thanks
