Actually that Sonic disc should hopefully include the burning program (like Nero) called RecordNow. Sometimes it's "hiding" on the disc.
Nero has been reported to cause problems on your drive with some regularity. But that doesn't mean most people will have problems, just be aware that you may encounter them. If it works fine don't worry about it.
Your drive also has lots of interesting tools available to it. Check the LiteOn tools guide in my signature for more details.
You can find my favorite method for backing up DVD's in my signature. DVDShrink is also a very popular freeware alternative. Check the trancoding forums for some greats guides that have been made up to step you through everything.
If you head over to the LiteOn forums and do some reading/searching on the 411S/811S I'm sure you will be able to find the answers to most of your questions have already been answered there.
Welcome to CD Freaks, I hope you find what you are looking for!
