A head's up. Two weeks ago I was copying a large data file from a DVD and I kept getting CRC errors. I didn't worry too much about it as everything else seemed to to be working ok. I thought maybe it was just a bad burn and didn't bother with checking it. Today I had to do the same with another set of media and the same CRC errors occured when copying the file. Knowing I had starforce installed, and multiple occurances of the error, I tried some other DVD's and had the exact same problem. Uninstalled starforce with their util, rebooted and now can copy the file with no issues. If you're getting CRC errors copying large files from media, simply uninstall starforce and reboot.
