[Bug 577465] Re: dvd / cd drives not handled correctly in 10.04 LTS

[KeithG]

Similar stuff here. Fresh instal of 10.04LTS. odd handling of DVDs . I
get this message in dmesg on each burned DVD that works fine in other
OSes and in a player: "end_request: I/O error, dev sr1, sector 9147640".
I have anotehr DVD that plays fine, but when I try to rip it to disk, it
hangs and drags the computer down horribly. Very frustrating. No
problems in 9.10...

The culprit:
