OK, So...
I just downloaded a couple ISO's of Windows 7, and checked them both to make sure they work by way of DAEMON Tools. Next step... Burn the 64bit one so I can test it out on my XP box.
I am using ImgBurn 2.4.2.0, Windows Vista Home Premium SP1, a LITE-ON DVDRW SOHW-1633S BPSA.
That didn't work. The image burned but it gave me a "Session 1, Track 1 is smaller on the disk than the image file" error.
I searched the forums, and found a prepackaged .exe for upgrading to SOHW-1653 CS0T firmware. I ran it and restarted.
I tried burning it again. It burned, but upon the verification process I got a shit-ton of errors before even making it to 10% verification. Here's the output:
