Got a new DVD burner (internal) a week or so ago and am having issues. It's a Sony DVD+-RW / +-R / CD, so in theory it should do everything. Well it plays DVDs, but when I go to burn something, it burns between 10% and 20% of the DVD, then craps out with an error. I've tried forcing the drive speed lower, I've defragged my HD (I'm trying to use the drive to back up my photography files), I've gone into BIOS and set user settings to disable the DMA. Nothing seems to work. If anything, it's actually burning less of the DVD before erroring out now. Device manager says no problems, the driver is up to date, and of course WinXP's troubleshooting is utterly useless. Any thoughts?
