Hi I have a previous model Panasonic DVD recorder, and have found that its fussy about which makes of RW disc itll play/record to. It likes Imation -RW discs fine, and some other makes of -RWs. And itll play panasonics dvd-RAM discs ok too. But it wont play Tesco's -RW's. Nor will it play/record to most +RW discs, despite the manual indicating they should work. And it almost seems like once the recorder comes across a disc it doesnt like, it seems to take a while before itll even go back to playing/recording discs it used to like before!
