I am not sure tlutz is the same thing.
First, I am a bit surprised hda is your DVD writer, but I guess it is me that is ignorant here.
Your values are a bit different:
  want=8350556, limit=7650048
and others where having something like:
  want=8475804, limit=8388604.
Oh well, maybe not that much, I think I will consider it affecting Gutsy too.

I don't have a DVD reader or writer yet.
But I sure know that by default Nero (suppose K3B too) on CD, have overburning (not sure of the name of the option) set on by default, that allowed to write more than the media would normally allow.
Hum, I will mark it as affecting k3b, that way, the k3b maintainer(s) could comment on this.

And I suspect you guys have 'overburned' your DVD.
Now, I suppose Linux kernel is checking size reported by the media, and limit it to it.
It should probably allow a reading the overburn area while reading.
But it is unclear how to.

This sure looks something that would not be specific to Ubuntu, I should
try to find information upstream or on other distros about overburning.
