A few weeks ago I was running Ubuntu Studio 10.10 amd64 and was able to burn dvds successfully with both Nero Linux 3 and Brasero. My dvd drive is an Iomega internal IDE that supports +/-/RAM discs. I recently upgraded to Mythbuntu 11.10 amd64 which uses the XFCE desktop instead of Gnome and while I can still read any format of disc with my Iomega drive, I can no longer burn any discs. I know this is a software issue because I just burned a dvd prior to making the upgrade.
I've tried burning an iso with both Nero and Brasero and both end with an error while burning the lead in. Nero exits with a "illegal disc" error. I've used dvd-rw (maxell), dvd-r (verbatim), dvd-ram (verbatim) and nothing works. I've also tried selecting the video dvd option in Nero and manually selecting the .ifo, .bup and .vob files and it still ends in an error.
I can't even successfully erase a dvd-rw disc. It will display the progress indicator as if it is erasing the disc and completes the operation without any errors. Unfortunately when I attempted to burn an iso to a disc that I had just erased I tried reading the disc after the error occurred and the old data was still on it.
Any idea what is happening? Is this a driver issue? What was changed relating to cd/dvd drives between ubuntu 10.10 and 11.10?
I forgot to add that I also installed a new SATA hard drive prior to making the upgrade. I have 2 IDE devices (master hard drive, slave cdrom) and 1 SATA device (hard drive) and I boot from the IDE hard drive.
Here's the output from "lshw -C disk"
