Ok, I am not a Linux newby but here is my problem. I have a CentOS 5.2 (final) release server running Kernel 2.6.18-92.1.22.el5. I used to have a Pioneer DVR-109 burner which decided to die (~5 years old) so I replaced it with a Pioneer DVR116DBK burner. These were/are attached to a secondary IDE controller as Master. With the 116 when I start Nero, Nero hangs on the scanning for devices sometimes for 5 or 10 minutes sometimes forever. If it should get past the scan for new devices I can click on Recorder -> Choose Recorder and the 116 shows up without issue. Now if I click on New to create a new compliation Nero hangs forever (it keeps taking up minimal cpu so its doing something and it is not really hung). Now here is where it gets Wierd. If I remove the 116 from the IDE bus and plug it into a USB - IDE adapter Nero works just fine and I have burnt a test DVD this way and it verified through Nero fine and even passed the double check I do with MD5Sum on all disks I burn. A dmesg | grep ide shows that the ide was using the ide-cdrom when it was connected to the internal ide interface. I have performed a yum update in the past 30 days so my system is current. I am at a loss and I have tons of data to dump to dvd from harddrive.
