I have a Samsung BDP-1500 and I use Verbatim DVD-R and DVD+R DL for my dvd copies. I have never had any problems with the discs before. Lately, I've noticed that my dual layer burns are fine but I'm having a heck of a time getting the blu-ray player to load any new DVD-R's. Old burns are seem perfect. It just tries to load over and over again and then it kicks out the DVD and says "Disc cann't be played". I can try several times and it will eventually load and play fine from that point on. I have tried the DVD-r's on several different DVD players and they load good too. I use Imgburn and have not touched any of the settings in the last year. I also do a "verify" after each burn and it is successful. What could the problem be? Thanks in advance.
