Best way to burn 9GB's of video files to a 4.7GB single layer recordable DVD?

I need to burn about 9gb of video files into a DVD for a friend. I'm doing it on a regular 4.7gb DVD. What is the best way to accomplish this? I have Handbrake, but I'm wondering if I should or could use the preset formats for iPhone, iPad, etc. She is watching them on a portable DVD player, so having them at full resolution probably isn't necessary. What free or trialware software could I use.

The 'InfraRecorder' and 'ImgBurn' are two free DVD burner programs. You can use them to burn your video to a DVD disc.

You can't fit 9gb of data onto a 4.7gb disc. You would either need to burn it as data files to a dual layer disc or split the files onto 2 standard discs. If you need the files to be in dvd format then you would need at least 2 dual layer dvds.

If your friend will watch the DVD on a portable DVD player, you'd better use a right program to compress and convert your 9GB video files to standard video dvd format then burn to a 4.7GB single layer recordable DVD, because only standard video DVD can be played fine on any portable DVD player, and you can use RZ DVD Creator to help you, easy to run this program, insert a single layer 4.7GB recordable DVD into your dvd burner drive, directly add your 9GB video files into the program, if you view a message tip "Source DVD size is larger than CD/DVD disc capacity", simply press "Yes", then press "START" button, the software will auto compress all video files and fit/burn on to the inserted one 4.7GB DVD as a standard video DVD, and your friend can watch this DVD on her portable DVD player. You could search and download RZ DVD Creator on google, hope it could help you.
