Other Hardware trouble playing back copies.

[beyedup]

i've been having problems playing copies lately on my dvd players. they are about 2yrs. old if that. i just recently upgraded my 1 drive to lightscribe coz old drive was shot. i check region codes and all good on drive and software.
the copies do play on the pc in the new drive. any ideas of what may be my problem with the dvd players. it plays original copies fine players. just not copies now.

If they play on the drive they were recorded on but no other, it usually means the disc was not finalized properly. Post the burn log from the last one you burned that will not play. Also tell us if the standalone DVD players give you any type of error message and whether you have changed brands of blank media recently.
