I have an LG DVD burner and a Samsung R121 DVD Recorder, when i burn home movies onto the DVD-R 8 speed disk It cant read the disk and it just ejects from the dvd player. I have tried the disks on other dvd players and they work but does anyone know why my disks arent palying in my dvd player. I have been using Princo dvd-r 4 speed disks and they are fine, but the place that i get them from no longer sells the 4 speed only 8. Please help!!
