does anyone know where to buy the above in Hua hin or thereabouts?

I don't know if it is open but my DVD shop called the Boomerang says that there is or will be a shop in Hua Hin, Hua Hin Market Village.

I have had good service from the local store here in Central Chaengwattana. If a disk is defective, it will be replaced at no cost. One time I changed disks three times and the actual reason was my DVD player had worn out. No complaints from the store. Worth a try.
