I'm definitely unconvinced about the possibility of bad media...

Retrying the burn process works, sometimes on first attempt,
sometimes after tray reload, and all checksums from original
files to the burned files are just okay. This happens with different
discs from different brands.

So far I had *one* bad disc - that would keep the light on my
DVD burner blinking forever until I hit the eject button, and
made my laptop (2.6.11-rc2-bk1) DVD player barf:

Jan 24 03:02:13 incident kernel: ATAPI device hdc:
Jan 24 03:02:13 incident kernel: Error: Not ready -- (Sense key=0x02)
Jan 24 03:02:13 incident kernel: No reference position found (media
may be upside down) -- (asc=0x06, ascq=0x00)
Jan 24 03:02:13 incident kernel: The failed "Read Cd/Dvd Capacity"
packet command was:
Jan 24 03:02:13 incident kernel: "25 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 "



Earlier FC3 kernels had another problem (that now isn't surfacing
anymore) that I described on the cdwrite list:
