I use Verbatim DVD-R discs in my DVD-RW drive but some of the discs wont read at times and at other times it will read, it happens to any disc randomly, the discs are in good condition and the DVD is almost new only a few months old and isnt used that much. It is also upraded with the latest firmware.

what should i do?
