You're going to need some free software. . .
DVDDecryptor, to write .ISO files reliably onto dvd (RecordNow packaged with some Retail BenQ drives works even better, but only slight difference).
DVDDecryptor also has other valuable talents.
Take a blotchy, rotted DVD original disc and use it with DVDDecryptor's all-file-mode with retries set to 1 and ignore-errors=on, and read speed set to slowest. Put the output through NeroVision or DVDShrink and you have recovered the rotted movie disc.
You can also use DVDDecryptor for testing data integrity with all-file-mode if you set ignore-errors=off (program then posts error message onto screen if disc is bad). This is useful for truely verifying a newly written disc under real-life conditions.
DVDShrink, because sometimes you want to fit a large movie onto a regular dvd disc. It has other talents too, such as creating a backup movie so you won't have to barbecue your expensive DVD collection by carrying them around in the car or RV to watch them in there. While this program can directly interface with Nero, I recommend that you send the output to either a plain .ISO file or send the output automatically to DVDdecryptor's ISO write mode. If you have an inexpensive http://club.cdfreaks.com/showthread.php?t=107490 or any other second drive that can read a dvd, then the two (above) pieces of free software can read, decode, rip, resize, restructure, package into .iso, burn, verify, and eject--all automatically.
CD/DVD speed, from cdspeed2000.com, can do quality write tests, and it also has a little-used feature like scandisc to verify data integrity. Warning!!: The popular quality control scan does not reveal any direct information about data integrity. What it does do is 1) let you see if the writing is in spec, and 2) let you compare your results with others (see our post-your-scans thread).
Note, eject newly written discs before QC testing. While you're at http:\www.cdspeed2000.com pick up the slightly crude audio extraction program and the disc speed controller. Together, those can get audio files off of a damaged disc, and you can also use 40x audio ripping.
