Though I’ve been doing CD burning for years I just got a Liteon LH-20A1H-184 DVD burner and plan to start making backups of movies. I’m totally new to this and don’t have much knowledge. Which is the best program Alcohol or CloneDVD with Anydvd? Is 4.7 gig disks ok or do I need the 8. disks? I just ordered Memorex 4.7 gig 16x DVD-R + disks. If a movie is DVD - can I use these disks, also are most movies done on + or - format? Sorry for all the questions gang but as I said this is totally new to this. Thanks for any answers you can give me.
