Problems and confused about burner and software

Hi everyone.

I have a question maybe someone here can help me with.
I’m having some problems with my Sony burner.

Before I go any further, these are all brand new disks right out of the packages. Disks that are recommended by Sony.

Now when I try to run decrypter and burn onto a blank dvd disk, I get the “disk if full” mesage.
If I try to burn using Nero, I get prompted for a blank CDR even though I’m trying to burn a dvd.
When I use the bundled software that came with my Sony, it works.
Why would that be?
But even more confusing, when I go the Sony support page to run a test on my drive , when I get prompted to insert a blank disk, the test won’t continue because the disk is supposedly not empty.

Any ideas?


Mods- I hope I didn’t do anything wrong by starting another thread in this section. If so maybe you can move it back to newbies? Sorry.
