Hello, this is my first post as well.
I've kind of got the same type of problem as you do. I bought a 100 pack of Benq DVD's, but mine are DVD-R. Burned dvd's will play in an Emerson DVD player, but not in my Toshiba SD/3860. It will just read the DVD for about a half a minute, then stop.
I burned some dvd's last night, and tested them out in the Toshiba, and they played just fine. I try them again today, and they won't play.
Not sure if it is the Benq DVD's, or the player, or what. Using latest version of Nero, have also used Sonic Record Now Deluxe.
My burner is only 3 months old. A Benq DW 1620. I've tried all kinds of things to get the dvd's to work in the Toshiba, even lowering the speed to 4X.
As to someone's earlier post about the Toshiba SD/3860 not being able to play DVD+R. I did burn DVD+R discs, and they successfully played with no problems. I am thinking this could be a problem with the actual Benq DVD's themselves. Seeing as you've had the problem with +R, and my problem is with -R.
Anyone got any ideas?
