I put in a DVD-RW into my Panasonic DMR-ES35V, in order to record something onto it. It asked me to format the disc in order to record over the material on the disc, so I did. The player then made a weird grunting sound and now I can't play any disc in it. There is a symbol on the player that says there is a disc in the machine all the time, even when there isn't. The videocassette stuff still works but the discs won't. Can anyone help me as I want to fix it.
