Sungale DVD Player, M/N: DVD 2030-5.1, S/N: SU2030CJ06d01733. The DVD played a few times and then "Wrong Disk Error"; it does not matter what dvd is used. Any workaround besides replacing the unit??
If the disks are commercial DVD movie disks, then it's the player. If the disks are ones that you have burned, it's possible that you have defective disks.
