My burned dvds won't play on other dvd players

I have SOHW-812s and all dvds I burn can’t be played on other computer or other dvd players.

I’ve been burning on dvd-r media TDK and traxdata. Should I switch to dvd+r?
Or is it because I’m burning with RecordNowDX?

Thanks…

Your problem is a bit strange. Can these discs be played on your 812? I can only guess that you are getting very poor burns. You can check your burn results with Kprobe 2.4.2 BLER scans(scanned at 4x scan speed the forum standard for comparison). You can read Interpreting PI/PO error scans to find out what these graphs mean. PI/PO is now referred to as PI/PIF. Roughly, PImax<280; PIFmax<4. Attaching disc quality scans to your post of the offending discs will help us help you.
