I used dvd-rw for my sony and they work perfect. Today i bought a TDK 50 pack DVD+R 4.7gb. When I try to add my video files which are 700mb, after the first video I get a message saying "the project exceeds some size limits of destination disc type, do you want to have project quality reduced. I don't know what to do. My sony supports DVD+R. What could be the problem?
