This might be an easy question but I'm new to all of this. I recently bought a Sony RDR-GX360 DVD burner, and I have no trouble recording the DVD's but they won't playback on any other DVD player. They will playback on the burner but none of the 3 other players in our house will play them, including our Blu Ray player. I've tried changed brands of DVD, but it didn't help. I started with Imation DVD-R 16x DVD's and tried Memorex DVD+R 16x after that. If I'm just using the wrong brand, could someone please recommend what I should use?
