Wont play DVD anymore

My old player, the DVD-RV31K, cannot play recorded medi such as DVD-R. I was not entirely aware of this and tried to play a DVD-R in it. I of course received the message that that type of disc couldn’t be read.

My problem now is that since that time, I cannot get the player to read regular DVDs :sad:

Is there some way to reconfigure the player that I haven’t found? Did trying to play the wrong kind of media (the DVD-R) somehow damage the player and it is now worthless?

Please, please HELP HELP HELP!

you may just need to try a lens cleaner, but it is time for a new player how about a DVD-S1 or DVD-S52?
