DVD S52 EGS-amazing performance

Attention please!!! I was very glad to find out this NEW Panasonic DVD player,able to play,according to Panasonic specs,also dual layer DVD+R-R, but after purchasing it,I couldn’t play any dual layer at all! So,looking carefully at the instructions,I realized that it “may” read dls only masterized with DVD recorders (!!!) and none of the ones PC burned. I let you imagine what I’m thinking about Panasonic brand! Thank you everybody.
