D8 to DVD-R?

2 yrs ago, I burned my D8 tapes from my Sony Digital Handycam into SVCD using ULead VideoStudio 6 (editing), Nero Burning ROM 5.XX (burning), & my old Yamaha 16/10/40 drive. All discs play on my standalone Pioneer DVD player.
Now I want to burn all my D8 tapes again but this time into DVD-R, for best quality and less discs. Will be getting Pioneer A07XLA drive and Ridata DVD-R’s. What software would be recommended? I already have ULead Videostudio 8, and I’m planning to get Nero 6 Ultra Edition? Basically same programs, newer versions. Are they still good? Or are there other suggestions?
What about programs like DVDDecrypter, CloneDVD, DVDShrink? Will they have any use for me (considering my main purpose) other than backing up DVD’s (which I won’t probably do)? Thanks
