I 2 T LG 731 readers (in the room and the kitchen) and all 2 do not copy dvd rw (more verbatim recommended by LG) Recording to HDD OK but when you want to copy the hard drive on dvd copying to (very long) and then when it's all over we read the DVD image is there but no sound (for 2 players I own) Sent to repair the first returned but the problem persists still no sound on dvd. So to avoid and also they are not given the price point of view given the poor quality of the product.
