Can boot from dvd player, but dvd won't work in Windows

I have an internal dvd drive on my laptop.

I can boot up from a Linux Live disc, but when I attempt to play a dvd in Windows 7 it won't play. The dvd player is recognized by the system, and I can even explore the files on the dvd. But when I try to play the files or copy them it doesn't work.

Since the dvd player works fine running a Linux Live disc it doesn't appear to be a hardware problem. I'm thinking there's some software fix for this.

I've had the laptop for a few years and this issue started in the last few months.

I've tried Microsoft's Fix It troubleshooting program, but it didn't help.

Any suggestions?
