Burning rom multo session

This question refers to do drag and drop writing (utilize burner like a hard disk/diskette) on DVD RW & DVD RAM ( i am using LG 4082 writer )

which NERO software produces DVD RW that is less prone to error; say I back up 1000 files ( overidding all of them everyday from Hard disk to DVD RW & DVD RAM )

  1. should I use Nero DVD burning ROM , multi session , should I choose the first option
    dvd ( iso) or 2nd option dvd …?

I think this UDF packet writing software produces errors in the longer run ?. 1) NERO InCD 4.0 drag-and-drop support
