I have the same problem with the error while reading. It doesn't happen to all the dvd but to quite a few. I also have a problem with the program freezing right in the beginning on the open dvd source. This doesn't happen with all the dvds but with a bunch. I copied and pasted the log session for today in here, like your help us help you said.
