[Help needed on Wii Iso burning!!!!!!!!!!!]

I updated the firmware for my DVD burner, even tried another burner (Sony). Bought DVD-R(Memorex, couldn't find Verbatim at my local store). I used Wiu to patch my ISO file. Still no luck. I used Gecko OS to load the burnt DVD. Always got an error saying "No DVD". So frustrated. !!

[Help needed on Wii Iso burning!!!!!!!!!!!]

I have a Wii ISO file saved on my hard drive. I tried using both Imgburn and Nero to burn it on to DVD-RW. I got a message saying "process completed successfully". However, When I checked the burnt disk. It was blank. File size is 0 byte. Of course, Wii will not read it. I did check, made sure it's in "write" mode. Not in "test" mode. I have tried many times with different ISO's. Someone please help!!!!!!! What did I do wrong?
