Hello there. I recently purchased a Pioneer DVR-630. I want to start recording to dual layer DVD-R but they seem impossible to find. I found a website(http://www.dvd-and-media.com/dual-layer-dvdr-media.htm) that sells Verbatim dual layer DVD-R but I am unsure if they would work in the DVR 630.is there any way I can check if they are compatable with my machine. Thanks.
