Hi. Any help with my problem would be great.
I have a NEC ND 1300a DVD Burner recently flashed with 1.0c firmware.
The problem I am having is with burning DVDs with data files on them. The burn process finishes perfectly, however when I try to access the files on the disk I get Cyclic Redundancy Check for every file! The discs are not dirty and do not look damaged in any way, leading me to believe it is a compatibility problem.
However, if I back up movies and run them on my stand alone DVD player (Logix DVD 3000) the film runs sweet as a nut! Running these backed up films via my NEC 1300a burner causes the film to be jerky and pause a lot.
The DVDs I am using at the moment are â€œRidisc 4x dvd-r with white printable surfaceâ€. They have ritek g04 dye which I though was supposed to be good (probably is if they would work!)

I have successfully written data discs using this drive with different media (Imation and Traxdata 8x DVD+R) and have ran a test on each media using DVD Info.
I have indicated in the media code above (using an *) the fields of data that are NOT present when running a scan of disc the Imation and Traxdata discs.
After reading the help file in DVD Info I found out that these fields are present on newer discs and allow the media to tell the burner at what speed to burn the disc (and other laser info), rather than relying on media support from the firmware. I have a feeling my problem lies in these fields because itâ€™s the only difference I can see between the â€œgoodâ€ and â€œbadâ€ discs that could pose a problem. Any help with my problem would be great. Thanks
