I'm having trouble playing DVDs. I've installed all the libraries and whatnot (ubuntu-restricted-extras, libdvdcss2, libdvdread4, etc.). I was getting a lot of I/O errors on my DVD drive at startup and when I tried to play a DVD.
But I just bought a new DVD drive and I'm having the same problem. I switched out the SATA cables and tried a couple different SATA ports on my mother board, so I'm pretty sure that's not the issue.
Basically, the situation is this. I start up and after BIOS loads, but before GRUB shows up, I get a quick error saying
error: cdrom read error. Then I boot normally, and everything is seemingly great. If I put in a DVD, it mounts, but I'm not able to play it or copy the files off of it.
I did a
dmesg | tail before and after putting in the DVD.

so no errors there. With my old drive I was getting a whole host of errors, none of which seem to be appearing now. Unfortunately they don't seem to be the cause of the problem.
Does anyone have any idea what's wrong or how I might diagnose this?
Just an update to the issue. I've just tried playing a DVD on the same computer running Windows 7 and there was no issue. So now I'm just confused. I assumed the error message at boot indicated a hardware issue, but Windows doesn't seem to care. So I guess it's just Ubuntu that has an issue.
