I also see this problem on two computers (A Thinkpad X200 with external LG USB drive, and a desktop system with an LG recorder). When copying data from DVDs, I sometimes get "input/output errors" with cp, and copying with nautilus fails, too, for files that seem to be beyond the first 1GiB of the disc. in dmes, I see lots of these:

I am running current karmic amd64 on both systems with linux 2.6.31-11.

On the laptop, unplugging the DVD drive helps sometimes. On the desktop, I have to reboot the system. After some attempts, I can read the DVD+R to the end, so it is no media fault.
