Forget about
Nero, it's turned in a piece of crap. I remember the days when you and I burned discs and
Nero was the only good program. My my, how things have changed.
ImgBurn is the burning-only redo of DVD Decrypter.
To read discs, DVD Decrypter often works still, but DVD Fab Decrypter is often needed on discs from the past 2-3 years.
FYI, your burner is a LiteOn drive, quite decent.
NOTE: Burning DVD+R DL discs is nowhere near as easy as single-layer DVD-R and DVD+R media. Just so you know. I still suggest Verbatim DVD-R or DVD+R, but know I prefer Verbatim DVD+R (I get less coasters). Sony "made in Taiwan" is another fine choice.
