Most writer software is fantastic in some area.
Those to avoid will install VSO's Patton Couffin Driver within Windows Device Manager.
The VSO based software will slow down your computer and introduce freezes into your movies.
Also to be avoided is Roxio's DirectCD, Sonic's DLA, and Nero's INCD as those three can interfere with other writing software.
My favorite method of backup up movies is to use DVDShrink to make an ISO and then send it to RecordNow (if available)(set to write-once) or DVDDecryptor for burning.
Favorite for data discs is Nero or Record Now (carefully set to a file system that supports multiple writes).
