In order to "fulfill all righteousness", here's the log from the ImgBurn startup (I had to move to the other computer), but now that I'm looking closely at it, it looks odd. The drive listed as #2, "I", is listed as "USB", but is a CD drive. The drive listed as #1, "D" is the DVD drive and is the one that actually shows up in ImgBurn. I'm not too familiar with this computer, so I'll see what's going on there. Meantime, here's the log:
