I own a Panasonic RP91 DVD player that no longer reads DVDs. Last week I rented a movie which played fine and the next day I put in Shrek for my kid and got a "No Play" message on the display after waiting more than a minute. I tried other DVDs I own and watch frequently and got the same sad result. For the heck of it, I put in a CD which the player read fine. Is the CD laser and DVD laser two different components? Does anyone have any service suggestions? Thanks in advance for any info.
