Finaly I can burn to a DL +R DVD. I use "Image Burn" which is the most simple software, you can google it and install in very easy, not much option which burn in the most basic manner.
For the burning DVD with using Image Burn, before you burn, make usre you unRAR the folder/files in a folder, you should see two folders and 10 files. Then select "Write files/folders to disc", then click "browse for a folder" small icon to select the 2 folders that you need to burn, then continue to select "browse for a file" small icon to select the 10 files you need to burn. Make sure after your selection, the window should show 2 folders and 10 files totally.
In right hand side, using write speed 2x, the slower the speed, the more the reliable.
Then you can start write by click the burn icon (bottom left side). You can either select "verify" or not. I'm not select but it work OK.
Hope it help the others that can't burn.
