Pioneer A03 power calibration error

[smithcomputers]

I have bought some 2x fws dvd-r discs but when i try to write at 2x I get the error POWER CALIBRATION ERROR if i try white label 2x discs they write but dont work in my dvd player. Any advise would be grateful and i apologise if this is in the wrong forum but my first time using a forum. DVD-R A03 firmware 1.90 rpc2. Many thanks....Mike.

I don't know exactly what that error means, but I use inexpensive DVD-Rs in my A03 that are rated 2x, and I have found recording and playback is most reliable when I burn at 1x. The extra write-time isn't a big deal for me.

Have you tried burning at 1x with verification?

I have seen it caused by three things.

1) Your Laser is on its last leg and it won't be long before you will need a new drive.
2) Crappy media can cause the drive not be able to finish its OPC(Optimum Pwr cal routine) prior to writing.
3) I have seen Nero do this after an Upgrade. I had to remove it completely and reinstall.

Its usually #2.
