- Writing Tests

We burned some DVD+R DL discs with DVD-Video content. The source disc was "Gladiator Movie - Special Edition" disc1 with a total size of 6.86GB. First we transferred the movie to the hard disc with DVD Decrypter as ISO format (single file). We used Double Layer media provided by Traxdata and Verbatim (MKM). The following picture shows the media code of these Double Layer discs.

You might notice that Traxdata media Id Code speed cannot be read by the drive. This means that this media is not supported with the current firmware the ND-3500A had. Former NEC drives had the same problem with Traxdata double layer media. We then used Nero CD/DVD Speed to see the supported speed.

Only 1X recording speed is supported by the recorder, making it impossible to write. However, we tried to burn the disc with CopyToDVD software, and latest Nero Burning Rom. We came up with the following error messages.

We then used CopyToDVD v3.0.29.48 with Verbatim Double Layer media, and specifically the "Movie & Pictures" option, and then "Write DVD Video". The software prompts us to select Video_TS/ISO image folder. We chose the "GLADIATOR.ISO" image and we selected the NEC ND-3500A burner.

After pressing "OK", the burning procedure started without any unexpected delays. It should be noted that we did change the default booktype setting prior to writing the disc to DVD-ROM booktype, with the latest DVDInfoPro software.

The writing process was finished after 22:52minutes, only one second slower than the TDK 1616N. The average speed was 3.87X as reported by the CopyToDVD software.

For comparison reasons, we post DL burning results with other writers, with the same disc content and same recording software:

The TDK 1616N is to date the fastest Double Layer recorder of all, but only by 1 second from the ND-3500A.
