DVD burner won't burn DVD but burns CDs

[darkertint]

I have a Sony DRU-500 DVD +/- RW. It has the most up to date firmware(2.1a). It stopping being able to write DVD in both video and data format. I tried different file types, and different discs. It just gets an error when I try to burn.
CDs will burn perfectly though.
Is there a way to fix this or is the DVD part broken?

What program are you using, and what is the error?

which are the upper and lower filters? i included a pic of what i have.
I'm using nero 7, before it stopped working, the dvds started to burn with skips in them or just stop half way through the movie. It use to all work perfectly.

Have you tried to reinstall Nero? Reinstall, and let us know what happens.

An easy way to remove the filters is to use the Guided Help here:

Make sure the drive is running in DMA, not PIO mode. This can be found in IDE channel properties.
