DVDFAB 126.96.36.199, I have the PBS series "Baseball". There are 10 discs in the set. I backed up the first 6 with no problems. When I try the seventh disk (titled '7th Inning') the program does the quick read, then I press start, it looks for the blank media (I have 2 dvd burners in the PC) then starts to read. About 3 to 4 minutes in, the program just shuts off - meaning it just disappears. If I look in the task manager, all traces of dvdfab are not listed. I have tried this several times using each of the burners as the read drive (Pioneer DVR-108 and DVR-110) with the same result. I then tried the remaining discs, and was successful. I do not see any scratches or flaws on the disc, and I can play the disc in the drives and in stand alone players with no issues. I sent a copy to fengtao (through dvdfab) approximately 2 weeks ago and have not received a response. Thanks.
