It is becoming increasingly difficult to find DVDs that work. Most new offerings from Sony, Maxcell, Verbatim etc are made in China and have a low reflective data side. I'm still having trouble finalizing these branded discs on my Pioneer 510H DVR. Pioneer says they hear a lot of complaints. They suggest using FUJI or TDK. Much luck.
