Help with region

When I try to convert my avi’s on my computer to a DVD burnable image and burn with DVD decryptor, I get a “Playback prohibited by area limitations” when I try to play it on my DVD player. However, when I play them on my computer, they are just fine. I first use DVD shrink and have set the DVD region code to region free and have also tried at set to only region 1. When I backup my other DVDs, they playback just fine. Any help is appreciated.
