Not sure if this will work for your player, but you can try this:
SPCA561 Drivers v1.0.7.8 (source:
Sunplus SPCA561 Webcam)
If that doesnt' work, then try this one:
4shared.com - free file sharing and storage - download
I've also attached a .zip file which you can download and install and see if that works as well.
I found this on the internet so can't claim credit for it.
Let me know if that works or not. If it works, I will upload it to MyMPx.org.
