That definetly sounds like poor quality media. Who manufactures the discs you are using? Also are you writing a 1x or 2x?

I writing at INTENSO DVD-R at speed x1 and x2 the same results
Make a test if you have a dvdr whith a movie and they dont play
at the end or at the last chapters freeze then turn up side down the
dvd-r media and look if the durning is clear stop at the end or
stop like faint not visible . I have many INTENSO here who have this problem can anyone have the same problem?

Can you run advdinfo or dvd decrypter on those discs to determine the 'actual' manufacturer.

By the sounds of your description it apears you got a bad batch or the manufacturer has changed to a different dye which is less reliable.
