After finalizing DVD's on my Panasonic HS2, I play them back on my Daewoo 5800. When I do, the finalized DVD's lose some of their fuctions such as Fast Forwarding x4, x8, X16...ect. & also U can't rewind, the player then freezes up. My friend has a different DVD player & the same thing happens to him. Is it the DVD-r's I'm using? Any help would B appreciated here.
