Writing DVD's in Intrepid ( 8.10 ) worked fine. Same hardware after installing Jaunty 64bit burning DVD images fail. Brasero, K3b and cdrecord from the CLI all fail. Same symptoms. Burning starts and get's about 18Mb or so, not far and then fails. Here is the output from a burn of an image created in brasero ( though all iso burn's fail ) I have swapped the DVD burner. Same issues.

Output from cdrecord with -dummy on so I don't keep trashing DVD's .. same output w/o -dummy.

cdrecord -v -dummy brasero.iso

Same hardware works fine in 8.10 .. There seem to be a number of DVD/CD issues in Jaunty but I couldn't find this same issue when searching. Reading DVD's works fine. It's just writing that fail's.

Anyone have an Idea ?
