Does this always happen? I know that I have once seen the system complainming about WRITE_BIG, and that was when I tried to burn a CD with more data than would fit on it. As a logical consequence, READ_BIG would suggest that the system is trying to read more data from a CD than is on there (?), but I doubt that this makes sense... If you only get this error message with certain CDs or DVDs, you may want to have a look whats different about these CDs / DVDs from those that do not produce the error message.
