I have a ASUS DVR-A04 2X DVD BURNER. I recently purchased 1X/2X DVD-r's (cake of 50) for some reason my burner only wants to burn in 1X mode. Could it be the DVD-r's cause they are so cheap, or is it my burner? I have updated the Bios of the device as well and can't figure out why it wont burn at 2X.... Btw if anyone has a 2X dvd-r how long does it normally take you to burn a full DVD ? With 1X it takes me aprox. 53 min.
