Hi guys,

I wonder if someone could help...
I've been trying to burn 2 new different media brands recently and they won't be recognized on my DVD player nor on my DVD-Drive. It's actually Princo (id code: Princo) and Ridisc (id code: Ritek GO4) DVD-R's.

The data are on the discs but they are not recognized, as if finalization did not work. Any one know what could have happened? Is there a way I can finalize a DVD-R once it is burnt?

Here's what DVD Identifier says:
