Pretty much that your burner doesn't like the media you are using. Could be a bad disc in a spindle. There is also only one speed to select from, so if the next disc also failed, you need to get another brand of discs.

I burned whole set of 25pcs of the same brand just before, but it's probably a bad disc. seems to be working with the next disc. it's going strong atm, passed 60%.

thanks for the info.
