Dear Sir,
The softwares that I have used are magic iso, infra recorder, and ofcourse Nero 7. Actually,I don't even have to use a burning software. Just inserting a blank dvd into the writer and right clicking and seeing properties, shows that there is no free space. I have tried 4 different brands of blank dvds available (Sony, Samsung, Writex, Moserbaer). Same result everytime.
But same rejected dvds are recording fine when I use them in linux(since I have two writers now) I can use live linux in one and another writer to burn.
