I appear to be having the same problems with buffer I/O errors on
/dev/sr0 or /dev/sr1. I can play, but not rip
My kernel logs look like this for /dev/sr1:

Many, many times over. The logs for /dev/sr0 are the same.
I saw medium error in the logs, so changed my dvds, but the same kept
occurring. I cleaned my dvd drives, but no change.
Output of hdparm:

I'm running Ubuntu 8.10 with an AMD phenom, on an asus M3A78 motherboard
(if it helps).
Output of uname is:
Linux mark-desktop 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64
GNU/Linux
/dev/sr0 is an internal SATA DVD drive and /dev/sr1 is an external DVD
drive.
If it helps, I was not having any problems like these on 8.04 - I only
started getting them when I installed 8.10.
Any explanations or advice would be greatly appreciated...
