I had a similar problem recently. I don't remember which version of hoster but I had a disk that holster wouldn't read the last track. Another diskk, hoster wouldn't read at all. I was using a plextor drive that I purchased from mtu. I tried both disk in microstudio and had the same negative results. I then tried a dvd drive (i/o magic) and it read everything with no problem. Maybe it is a quirk in the drive you are using.
