Error: unable to analyze disc layout

[464cowboy]

Started getting this message. I installed a new video card about a day and burned about 15 disk now this is the message I get.

Also got Load disc: Command failed on device 1.10 (04h 00h 02h 02h 3ah 00h)

I checked my new plextar px5224a on burning other disc's it works great. I had computer problems so formatted hd and went from widows 98se before stripping and went back with new XP sp1. My computer is a dell PIII 700mgz with 256mg ram new ati 128mg agp2x video and new plextar px5224a.

I have ordered 256mg of more ram hoping this will fix. But don't understand why it was working and now quit.
