This is a strange problem.
When I first got my Pioneer A03 from vidioguys it came with Pioneer DVD-R disks. I was able to make dvd's with no problems.
Then I got some more Pioneer DVD disk and I would get a error when I try to burn a dvd. This happens with TDK dvd disks too.
The ones that do work (by trial & error) are Samsung DVD-R disks.
Here is the error:
"Error-10 at Sector 624- Disk Read Error- Command:2A Sense:03ASC:73ASCQ:03"
This happens if I try to author a disk or make a data disk using Prassi PrimoDVD 2.0 and with DVDit PE 2.54
