Unfortunately you aren't able to simply use a program like Nero or Roxio to copoy you DVD movies. The reason for this is that most of the DVDs that you buy in the stores have some type of copyright guard or protection on them. Because of this protection, your computer isn't able to recognize the disc and read it properly.
This doesn't mean you're out of luck though! You just need to equip your computer with the right type of software. Once you have the right tools, it's a snap to make a copy of any DVD you want.
There are now software companies that have developed DVD burning programs that can bypass these copyright protections and allow your computer to make copies of your DVD movies. Because the software can get past the guards, your computer is then able to make sense of the data on the DVD movie disc.
As a side note, most DVD movies are recorded on 8GB DVDs. However, most blank DVDs are only 4.7GB in size. Don't worry though - the best DVD burning programs will be able to condense the data so that it will fit on the smaller size. You can buy 8GB blank discs, but they are a lot more expensive, so this feature is a great one to have in a DVD burning program.
There's a few DVD burning softwares you can choose from, but make sure that you pick one that offers you updates. The reason for this is that every now and then new copyright guards are invented and the software must be updated so that your computer can bypass these new guards. The best DVD burning programs will offer this feature to you.
I also like to see a moneyback guarantee offered. This way if there's any problem with the program I can get my money refunded. The companies that are confident in their software won't have a problem offering this.
Having a DVD burning program is a great way to backup all your DVD movies. Once it's installed, you can copy any movie you want with just a couple clicks of your mouse. Enjoy the show!
