For annoying reasons, you just can't seem to get a standard CD drive to read a DVD disc. I was wondering if anyone had any suggestions to help me solve this problem.

You can't. Only DVD drives can read DVDs.

I thought as much. So your telling me that there is no kind of software that I can install that will enable DVDs to be readable?

You would need a hardware installation.

Yes, there is no chance in hell you can get a CD-ROM to read a DVD, they're built differently than CD's and require different equipment to read them. I don't know how they work exactly but it's the god's truth.

The data track of a DVD is much tighter packed than the track of a CD. Do the math: Constant area of the CD/DVD, but a DVD has a lot more data on that area. So the density increases. CD-ROM drives simply can't achieve the degree of precision needed to read a DVD.

nope.... buy a dvd rom... kinda cheap by now...
one reason is that data is stored a bit different on a dvd... for example... dvds are multilayer :)

Yeah buy the DVD-ROM, a no frill version is like $20 anyway. Extra like MPG card (for better performance) or DVD player software like WinDVD would cost more.
Here's a run down of why CD-ROM can't read DVD. typical CD player and CD-ROM uses infrared laser, which is of longer wavelength but cheaper. The track and data of DVD is much more tightly packed and they spin at higher rate than CD (1x DVD is much faster than 1x CD), and some DVD can be dual layered for double data. Because of this, infrared laser won't work. Red laser is used instead.
Next generation DVD would be using blue laser, which is of much shorter wavelength and would allow 100's of GB per disc vs about 5GB for single layer and 9GB for dual layer.
Fortunately, laser of shorter wavelength is backward compatible with older media using longer wavelenth so that's why DVD player can play CD and CD-ROM easily.

*bangs head against the wall*
Shoot! The reason I was asking was because I needed a DVD that would actaully BURN DVDs. Unfortunatly, they cost around $250 at Wal*Mart. *grumbles* Maybe E-bay (yes, I am scrapping at the bottom of the barell)?

Well, if you want to burn DVDs, then you would need a DVD Burner and not a Rom Drive. A DVD Rom Drive only plays DVDs.
