Bought a load of DVDs thinking I can play them through the Samsung SE-208GB/RSGD which I already have to my Panasonic smart TV. I just can't get this to work although it's supposed to. Am I missing something here? I connected via the USB but although the thing lights up it doesn't work and doesn't appear to be showing in AV. Any help appreciated because despite loads of google and youtube I'm finding no answers.
