Need Help Playing DVDR on Sony s530d stand alone

Hello. I’m a greenie in the field of DVDR backups still and have a question about playing a DVDR in my stand alone DVD player. I’ve tried using online compatibility guides, but can’t get either a -R or a +R to play in the unit. I don’t want to keep trying without knowingly trying something different, that will be expensive, but I’m looking for someone that had/has this unit and any type of help in regards to the success/failure you’ve had in playing DVDR’s in the unit. I use DVD2SVCD in the DVD2DVD mode with CCE and Sonic Scenarist and Nero 5.5.10.42 to burn.
I have been following AZImmortal guide at
