can't read just burned dvd+r

Correction: it works with cdr.

I have disabled automount in nautlius, it still [r]ejects burned dvd+r

What about if you burn as slowly as you can?

Do dvd-r disks work? Is your drive a dual format drive (newer drives are but some older drives aren't)

dvd+r written with 4x speed can't be read.

I'll try dvd-r later on, when I get one.

Easy over look try closing the disk if your not going to reuse it. that can couse conflicts and read errors, take a disk burn it and close the disk with the burn and see if it reads it then, you can at least narrow your problem down..

dvd+r still doesn't work
dvd+r burned on another (windows) machine doesn't work but with different errors - VFS errors included below.
dvd-r burned on my machine, 4x, closed session - *works* - WHY?

Brasero gave me option to turn off session closing - on by default, but only for dvd-r, not for dvd+r. With Xfburn I can at least choose mode. It looks like all those disks were burned with closed session.
Xfburn, tao, 4x - fail

Reading all these disks makes sounds of searching for track, with different rotation speeds. Only dvd-r works and dvd+r burned on another machine shows errors in dmesg.
The drive and sony dvd+r not good enough to work together?

Log a bug is all i can suggest. Or upgrade firmware in drive (risky)

Broken harware :-(
