The CRC error is on the source DVD, not the target DVD. The source plays fine,
so the error is not blatant. Even Nero thinks the DVD source is ok when I check
it's status. What kinds of error messages does one get from Nero when the source
DVD is read protected? Might a protected DVD show up as having CRC errors?
My drive is ok as I have copied other DVD's with no problems.
