I have a few questions about the CRC check module in DVDInfopro.
First, I understand that the red blocks indicate there are CRC errors in data blocks on the disc being tested, but I am wondering what manifestations one can expect with playback. I have noticed that one or two red blocks on a disc have not demonstrated any appreciable playback problems, but when I have several, especially several in a row, there seems to be a jumping, skipping or freeze in playback. Is it accurate to say that a few red blocks will not affect playback in a noticeable manner? Or have I just been lucky with the discs that have only a few red blocks?
Also, I have noticed that some red blocks appear quickly, without a test on individual blocks being performed, while others appear after a long test of individual blocks? What differences is there between those two red blocks? Or is there?
