Errors burning CD's/DVD's with Trisquel GNU/Linux 4.0.1

Hi Everyone,

Since I've tried Taranis 4.0.1 and Ubuntu 10.04, I've been getting errors while burning CD's(700MB) and DVD's(4.7GB and 8.5GB DL).
I've tried doing it both with by Desktop and my Laptop, I'm getting the same outcome.
I've tried with Gnome Baker, Brasero and K3B.
I've been trying with Memorex, Verbatim and TDK CD's/DVD's.
On the Desktop I have a Plextor PX-740A IDE, on the Laptop I have a Matshita.
Is anyone having the same problem? Is there a bug reported regading this issue? Has anyone found a solution?

Thank you very much,
