In addition i have to tell you that after trying a few discs it didn't open the last files . For example i made a dvd with 6 divx movies, then it would be the last two or only the last one that won't read. Is it possible because i burned the discs the one after another that caused this to happen (is it possibly for burner to get overheated)? I have a Sony dvd combo that opens all files which NEC can't. It doesn't matter if it's a multisession disc or not.
