Hey guys, I am having issues decoding and burning a dvd. I am using DVD Flick to encode the video I have, then when I use nero to burn it, it stops as soon as it begins saying

Illegal Disc
E: Lite-On DVDRW SOHW-1633S

I tried using a Memorex 4.7GB DVD-R and a Maxell 4.7GB DVD-R.

Please give me some ideas on what the issue is! thanx!
