I read this tutorial before I wrote the email. But the device
wasn't mounted and I didn't try to access the auto-mount-point.
As long as I understand the "autofs" daemon, the device is used
when the device is mounted or I try to access the mount-point.
May be I'm wrong in this.

But I had better results, when I recompiled the kernel (2.4.23)
with DMA on for CDROM. I didn't change the autofs setup and
a DVD+R was burned fine and plays also as expected.

But now when I try to burn a DVD-R (Verbatim media) it burns
and at the end I see the following:

1513848832/1529421824 (99.0%) @2.0x, remaining 0:05
1523122176/1529421824 (99.6%) @2.0x, remaining 0:02
/dev/scd0: flushing cache
/dev/scd0: updating RMA

/dev/scd0: closing disc
:-( unable to CLOSE DISC (2h/30h/05h): No medium found
/dev/scd0: reloading tray

At the kernel level ("dmesg") I didn't see an error.
Any ideas?
