Hello, can anyone help with what to do if certain DVDs don't play on my
Dell Inspiron 640m laptop. VCDs and some DVDs ok. Thanks! Sarah

Have you checked the region code of both the DVD and the DVD player to see
if they match? The region code of your DVD player can be accessed (and
changed, but only 5 times IIRC) in the device manager under advanced
settings for the drive. See:
