I installed the Samsung SH-S223L DVD writer into my case, and it started off just fine. Windows 7 installed fine, all my driver discs worked fine, etc. But it won't play commercial DVDs. It reads software, plays commercial and burned CDs, plays burned DVDs, and recognizes blank CDs and DVDs, but if I put in a movie, it spins, then makes a weird "creaking" noise and just keeps trying to read it (and failing).
It's set to Region 1, I updated the firmware, and I tried reinstalling the drive and IDE controllers, but still no luck! Help, please?
