I am having problem buring dvds. I backup the dvd with DVD Decrypter and burn with InterVideo DVDCopy 3 but few days ago i stated getting coasters. but i didn't get any error message. it said burning success / completed. no errors at all. When i look at the disk it only used half of the disk. i can clearly see the line on the dvd. I tried to play the dvd but it doesn't play. I did uninstall/install the intervideo dvd copy 3 but still getting coasters. Everything was fine before. i used the same dvd media and everything.
also tried with dvdshrink ...same result.
my burner is Nec 2500a and firmware version : Herrie 1.08v3-2
