The point is that you are the only one having this problem to this extent. No one else has said they have trouble with it except Billyo and his is not consistent as you are saying it is. From the pictures you sent I can see some garbage but it is not messed up to the point it is not usable.
Make sure the firmware for all your drives are current. Clean the drives with a laser cleaning disc. And even if your discs are pristeen clean them as well.
I don't know what else to tell you to try to get it working right for you. I cannot duplicate your problem and none of the Beta Testers have reported anything like this with the current release.
