I'm having a problem with erasing a movie on the disk and then trying to record something else to the disk. The disk acts like there is no time left. I have 4 disks now that have done this to me. 2 are TDK and one is a memorex. I don't understand why it would do this. Can you help me figure this out? I thought that you are supposed to be able to tape as many times as you want on these disks. I want to see if I can fix this problem. I don't want to toss these dvd's without trying to fix them first. Can someone help me? Thanks
