Forget about Nero, it's turned in a piece of crap. I remember the days when you and I burned PS1 games and Nero was the only good program. My my, how things have changed.
ImgBurn is the burning-only redo of DVD Decrypter.
To read retail discs, DVD Decrypter often works still for tv shows and old movie DVDs, but DVD Fab Decrypter is often needed on movies 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.
