I routinely check my freshly minted backups with DVDInfo Pro, looking for CRC read errors. I have always had good playbacks if the test shows no errors. Now, with "Cop Land" I got a perfect test, but the title falls apart right from the beginning. It does this on my Sony standalone, as well as on the computer using Power DVD? I tried the test again after playback failures and got the same result - flawless. I ripped, as usual, with DVDD and burned with Shrink. As I recall, the compression wasn't extensive. I'm willing to try again, but other than just changing a few variables, I'm not sure how to avoid this issue.
