darthrush - are you using the pioneer BDR-XD05? If so that’s that one I have and even reviewed off amazon. I’ve had great success with it since early this year for DVD, DVD9, and BD25. I’ve stuck mainly to plexdisc (the glossy printables are amazing), letting imgburn auto detect the max write speed, and I’ve not had any coasters or failures. I second that verification is a time sink, but is a good idea to do as my previous Laptop DVD burner did fail me once. I will say that my PS3 played the BD25 smoothly, but I did run into a little spat of freezing (medal award sequence in SW) on the PS4. So I threw in ROTJ just to see if might be a consistent bad burn/burner combo. Nope. Then I played SW again. Nothing. So I’m sticking with the plexdisc moving forward for the BD50s and see what happens.

I have to say that BDR-XD05+PlexDisc Liquid Defense Glossy+Canon Pixma922 = Amazing Dics!
