FWIW, I happen to experience the same with the latest
 FC3 kernel on my Samsung TS-H552 burner; that is,

1. CD burning works 100% of the time
2. DVD burning may fail with EIO (nothing in kernel logs)
3. retrying burning usually works

Yes, I resorted to only use DVD+RW media now since the
 ratio of coasters has made +R more expensive than +RW :(

Last night I had to insist quite a lot with my burner's eject
 button before it decided to open and let the disc out (this
 particular session after failing once at 61% with EIO would
 reliably fail at the initial write). After reloading the tray
 with the same disc, I successfully burned it.

NB - this happens with Memorex and Verbatim media,
 not with el-cheapo discs.

I'm available for eventually testing of the 2.6.11-xx kernels
 from kernel.org (another side-effect of moving from RH9
 plus kernel.org kernels to FC3 and its own kernel is that I
 no longer have a dead machine after the updatedb run,
 which would happen about twice a month on my 256MB
 RAM k7-800).
