I helped my brother set up his DVD burner using Nero - we were able to succesfully burn several DVDs which would play back just fine on the computer and on my Panasonic DVD player. But - they will not play on his Sony DVD player - he just gets "error". I thought I had read somewhere on this forum that there was a problem with Sony DVD players wanting only Sony DVDs but of course now I can't find it. Does anyone have info on this? He's written and called Sony customer support but they are no help at all. Thanks.
