Ah, my first Help Desk thread.

Let's see if you all can help me out here.
The other day, a friend of mine came over and installed a DVD drive for me. Specifically, it's a LiteOn 16X DVD+-R/+-RW. I assumed my computer already
had a DVD drive before, so when I received a DVD-RW with anime on it, I thought I was all set. Unfortunately, I just had a CD-RW drive so that's why I needed a DVD drive installed.
Anyway, after being correctly installed (the same friend installed other things for me onto an older computer so I'm sure they knew what they were doing) we put in the DVD-RW and nothing happened. Not even the usual box Windows pops up appeared. (The one that asks what you want to do with the files on the disc.) I figured, well, maybe the DVD I received was messed up. So I put in an official DVD I knew worked. The folder containing the movie opened, so I double clicked the icon, and got the hourglass cursor for a few minutes, but that was it. The computer didn't freeze or anything, but the movie just wouldn't play.
My friend and I emailed LiteOn asking for help but got no answer. He thinks that Windows sees the DVD drive as a CD drive, because when we checked the properties of it, it said CD drive. I tried changing it back but it wouldn't stay.
Is there anything I can do to make Windows realize this is a DVD drive? ;__; I want my anime. If you need the specs of my computer, I can give you that.
EDIT: Oh crap, I thought this was Help Desk.

I need to not have so many tabs open at once. Can someone move this for me?
Jam it back in, in the dark.
