I bought a Pioneer A05 DVD/CD burner and I have it installed in a Pentium 4/Soyo Dragon computer with Windows XP Home and a Voodoo 3 3500 video card. It seems to play DVD's ok, read cds, and burn cd-r, but I cannot get it to burn DVD-R or RW. I've tried several different programs and they all just give error messages. I put the drive in my other computer, a Pentium 3, and it works fine! I sent it in to Pioneer and got a replacement, but it has the same problem. Has anyone heard of this problem? Thanks.
