I am appreciating the help, but this is getting way too complicated for just adding a DVD burner. I wish I'd just bought the PATA burner I opted out of (only because I wanted to make a small number of Lightscribe Labelled discs for my Mom for Christmas, which obviously didn't happen anyway). I can still buy one, but that's another $40 I can't afford, and I can't take this one back because when they test it I just know that it is going to work fine for them (they'll burn a 10 Mb data disc and send me on my way).
Here's an idea I had, but I don't know if it is possible. Since the burner works fine for data disc and the software seems to try to create the track files from my Wave Files (or MP3s), is there a way I can create and Audio disc image that is like some kind of raw data that gets burned onto the disc without the burner knowing that it is making an Audio CD). It doies still need to work in stand alone players though.
Otherwise, as far as controllers go, both computers had trouble. The original computer is SATA 1 with ATI Controller. The controller says it is ATI IDE controller, but beneath it are listed all the individual controllers as IDE (I assumed this is SATA under some kind of IDE emulation or something because the hard discs work fine and the burner and disks all say the are Ultra DMA Mode 5 and 6 respectively.
On the other computer I tried, they are AMD controllers called "AMD SATA controllers (native IDE Mode)"
I can't find any driver updates for Sata drivers on the manufacturer of the mainboard...only VGA, LAN and AUDIO drivers. If you need more info than that, I'm afraid I need to know how to find it because I'm not sure what precise info you are looking for. Should I try uninstalling the controller drivers and go with XPs default drivers--that sounds like a really bad idea though someone suggested it to me. I trust microsoft about as far as I can throw the moon. With so many damned compatibility issues every time I add new hardware or software, I feel like buying a Mac (can't afford one) or kijiji-ing for an old Amiga (of course I don't think they had DVD burners back then). Thanks for any and all help.
