"But, you could try using a Lens Cleaner DVD and see if it can make a difference."
"... hardware failure, usually the Spindle motor,"
Then logically a lens cleaning DVD would not work if the spindle motor is not working. Is this correct? Is there a higher than 90% chance a DVD lens cleaner would be a waste of money in this case? $10 for a DVD lens cleaner. $20 for a new DVD player/burner.
