DVD Tests
Pioneer DVR-A04 supports both 1X and 2X (CLV) writing speeds with DVD-R format. As you may know the X factor in the DVD format is not 150Kb/s but 1385Kb/s meaning that a full DVD-R (4.38GB) will take around 60mins to be written at 1X and half the time at 2X writing speed (30minutes). The DVD format is simpler than the CD, since you have only "Mode1" tracks and "DAO" writing mode.
- Writing Performance
We used Nero 5.5.7.8 and wrote the same amount of data for all Pioneer DVR-A03/A04, Ricoh DVD+RW MP5120A and Panasonic LF-D311 drives. The results are listed in the following table:

Pioneer DVR-A04 took 28:15mins to write an almost full 4.7GB disc. The recording time is better than that of the DVR-A03 (by 8secs). At the 1X writing speed, the drive will take almost one hour (56:21), which is again better than the DVR-A03. It's quite interesting that the drive needs less time with DVD-RW format at 1X than with DVD-R media:
