Memorex did go through a bqad patch, which I understand was due to the fact
that they used more than one supplier, of which at least one had
less-than-adequate quality control. I don't think there is a problem now.

Not all older drive support burn-free, which could be one factor.
I haven't seen any clear correlation between age and vulnerability.
Old Samsung SCR-2432 and SCR-3232 CD drives from 8-year old boxes aren't
vulnerable.
Another thing to consider. I was told by Lite-On technical support
people
that DVD+R disks are more forgiving than DVD-R. I have certainly had fewer
problems on my stand-alone recorder since changing to +R.
I've seen technical articles (which I don't fully understand)
explaining the many reliability advantages of the plus format over the
minus. I always use plus. It's no more expensive anyway.

Yes, I've burned many DVDs under FC6. I use K3B, and have no problem at all.
Anne
But what about command-line cdrecord? K3B and other graphical tools
all probably choose automatically between cdrecord and growisofs, and
I'm guessing that with DVDs they always use growisofs.
