- 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 screenshots show the media codes for these Double Layer discs.

Acording to NEC's supported medialist for the ND-3520A, only Verbatim double layer media can be burned at 4X. All other media were burned at 2.4X.

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 not change the default booktype setting prior to writing the disc to DVD-ROM booktype, in order to investigate the default booktype setting for this media type.

The writing process was finished after 22:35minutes, even faster than the ND-3500A burner. The average speed was 3.92X as reported by the CopyToDVD software.

We then repeated the same procedure for all media shown above. The following table indicates the recording times for double layer media. As you can see, the Verbatim double layer media was the fastest of all, since it was the only one that could be burned at 4X.

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