pioneer slot-loading DVD won't play DVDs (will play CDs). Thoughts?

[nickburger 0]

I recently purchased a (used) Pioneer DVD-104 slot-loading DVD player. I hooked it up and tried playing a CD (music). This worked just fine. However, when I go to play a DVD I'll insert the disc, it'll act like it's reading for about 5-10 seconds, then spit the disk back out.

 

So far I've tried installing WIN-DVD as well as installing ForceASPI version 4.6, with no luck. Still won't even keep the disc inside the drive.

 

Any thoughts? Does it sound like the drive might be bad (I was told it was a working drive)? Is there anything I am doing wrong to get it to refuse to read the disc? The only experience I've had with DVDs is the one in my laptop, which obviously came pre-installed. This drive came with no driver/software discs and is supposed to be PNP.

 

I'm running WinXP on an AMD 1800.

 

I appreciate any help.
