To Customers Who Use the Pioneer
DVR-A03, DVR-A04, DVD-104 DVD-R/RW writers

We appreciate for your patronage to use the Pioneer DVD-R/RW drives.
The DVD Forum has established the new standards for high-speed recordable discs (DVD-R discs supporting 4x recording and DVD-RW discs supporting 2x recording). These new high-speed DVD-R/RW discs are scheduled for market introduction soon by various media manufacturers.

In tests to check the operation of these new high-speed recordable discs, Pioneer has discovered that the DVD-R/RW writers (DVR-A03, DVR-A04, DVR-104) may malfunction, if used with new high-speed DVD-R/RW discs. This issue is caused by the device's inadequately programmed firmware, which may cause damage to both the device and the inserted high-speed disc.

Pioneer therefore would like to request customers to download the firmware for updating the writer directly from the URL provided below. Once the writer is updated, it will be able to use the new high-speed DVD-R/RW.

Pioneer deeply regrets any inconvenience caused.
