There are many things you can ask that buyer to check.
How old is that DVD player and it runs any other region 4 DVDs without any problem before?
Are there any scratches on the back of the DVD?
Have the buyer try the DVD on another DVD machine or from a computer. Also ask a friend, neighbor, relative or co-worker to test it on a different machine to make sure it's the disc problem.
If you really don't believe what buyer says, you may also ask him to take a video shot, upload to YouTube to actually show you it indeed does not play |
