I'm backing up my entire Star Trek: The Next Generation collection - VERY valuable to me!

I've tried doing it from disc or ripping it with DVD Decrypter and DVD Fab Decrypter and then doing it. Neither ripping program has given me any problems with taking the data from the disc BTW. I have also tried it with a friend's disc from his collection and the same problem occurs so I have no idea WTF is going on, as all the other discs copied. If it's relevant, my DVD drives are both Lite-Ons; one is SOHW-1633S and the other is SOHD-167T.

As luck would have it, the very last disc that I am doing - series 4, disc number 3 is giving me big problems. If I try to DVD-Shrink it, it gets no further than 1% of the initial speed-analysis and tells me: 'Failed to read file "F:\" Invaid access to memory location.'

If I do it with Clone DVD, at 76% of the file preparaing, it always tells me: 'unexpected error'. The details are just "Clone 1 TCE". The log's here, sorry I couldn't post it as an attatchment but it's too large in file size.
